Topics (A-Z)















Follow the International System of Units (SI) as a guide for units of measurement.

Degree titles take the following form: BSc, MLitt, PhD.

Do not use full stops in abbreviations: eg, am, pm, op, no, cf, ie, ed, etc or after Mr, Mrs or Dr.

Spell out abbreviations/acronyms in full when they are first mentioned in text, for instance: Department of Mathematics and Theoretical Physics (DAMTP). Also consider adding a glossary to longer documents, especially for non-technical readers. By default, acronyms are all in capital letters eg CITIID, COVID-19, DAMTP.


Use open punctuation in addresses:

University of Cambridge
The Old Schools
Trinity Lane
United Kingdom
General switchboard: +44 (0)1223 337733

Alumni affiliation

Where the words alumnus, alumna, alumni or alumnae appear, they should be lower case. Alumni is the masculine plural noun and should be used when referring to a collection of male and female alumni. Alumnae is the feminine plural noun and should be used when referring to those who attended women-only Colleges Newnham, Lucy Cavendish and Murray Edwards (formerly known as New Hall). The masculine singular is alumnus and the feminine singular is alumna, for example Dame Emma Thompson is an alumna of Newnham while Sir Ian McKellen is an alumnus of St Catharine’s.

Where appropriate, after a person’s name you may put in brackets the name of their College followed by the date of matriculation. The subject can be included, but for normal usage the College and matriculation date suffice. There is no comma between the College and date.

Bold text

Limit the use of bold text to improve readability. For email and web content, you may use small amounts of bold text to make your text easily scannable. Use of bold in this way will create focal points for the reader. However, too much bold will have the opposite effect and make the text difficult to read.

Bullet points

If you use a complete sentence to introduce the bulleted list, then end it with a full stop, not a colon.

  • It is important to start each point with a capital letter.
  • Remember to end each point with a full stop.
  • It may also be helpful to use single spacing between single line bullets and double spacing between bullets if longer (paragraph-like) lists are used.

When working with lists of points that are not full sentences:

  • Place the colon at end of sentence introducing the list
  • start points with lower case letters (because they are not complete sentences).

Capital letters

Use lower case as much as possible. There is a tendency for people to capitalise words unnecessarily just because they are deemed ‘important’. Resist this. Company names may feature unusual capitalisation (or lack of capitalisation), try to follow the company’s convention, even if it looks ridiculous.

Use sentence case in headlines: Teachers from state schools learn how Cambridge really works
(not 'Teachers from State Schools Learn how Cambridge Really Works')

In text use a capital first letter if the noun is specific: the Faculty of Education, but use lower case letters in general use.

The University uses capital letter U, when referring to the University of Cambridge. When university is used in a general way, eg a place at university (meaning any university) the u should remain lower case.

The Cambridge Colleges use a capital C, even when referring to the Colleges in general. This differentiates the Colleges from further education colleges, for example: the Colleges admit students from many local schools and sixth-form colleges.

Capital letters are used for positions/job titles such as Senior Tutor, Admissions Tutor and Director of Studies.

Degree titles use initial capitals, eg BA Honours in History. Single Honours, Joint Honours, etc also use initial capitals.

Initial capitals are also used for term names, eg Michaelmas Term (Oct–Dec), Lent Term (Jan–Mar) and Easter Term (April–June). May Week, which takes place in June, is also capitalised.

Qualifications should also be capitalised eg GCSEs in Mathematics, Chemistry and History.

Significant words in titles of books, magazines and newspapers take initial capitals (aka title case), and the titles of periodicals should be in italics. However, 'a', 'and', 'at', 'for', 'from', 'in', 'of', 'on', 'the' and 'to' are not usually capitalised (except at the start of a title). Only two UK news outlets use full italics in their titles: The Times and The Economist (in contrast to The Guardian or The Independent).

Titles of papers/journal articles should have initial capital letters eg This includes the paper 'Historical Argument and Practice'.

Follow a colon in headlines with a lower case, not capital, letter.

Use lowercase letters and no hyphenation for phrases such as cleantech, medtech, fintech.

Permission must be obtained to use any material (charts, illustrations, photos, illustrations, etc) that has not been originated by the author (this is usually done by submitting a written request, detailing the material and the context in which it will be used). Once permission has been confirmed then identify the source as an image caption or footnote text: Reproduced by permission of xx or © Photographer name.

Always source quotations: Professor Daniel Smith, Head of Divinity.

If something looks as if it could have been taken from another source, query the text or image (and it never hurts to cross-check via Google). If there is a substantial amount of someone else’s material used without credit (=not original), then question its value/avoid using it.

Country names

Use the English-language equivalent (Germany, not Deutschland) and list any sequence of names in alphabetical order.


  • Friday, 16 January 2004 (not 16th January)
  • 1890s, 1930s not 1890's, 1930's
  • 20th century not twentieth century (use 19th-century only for adjectives: Late 19th-century architecture saw an increase in heavy detailing. Leave th or st as roman, not superscript).

Use two digits when representing a span of years within the same century: 2009–10, and four digits: 1892–1925 when spanning more than one century.

Dates are expressed as date/month/year, eg 1 July 2017, or Monday, 1 July 2017 (note the comma following the day of the week).

See also: numbers, time


Cardinal points of a compass (north, south) are only capitalised if they are part of a title: North West Cambridge, Eastern Europe, North Yorkshire, but not as part of general descriptions: western Canada, southern Scotland.

Email and web addresses

Email addresses and URLs should appear in lower case, eg and Do not include https:// at the beginning. End with a full stop if the address appears at the end of a sentence.

Avoid underlining email addresses or URLs. (Note: some email software may automatically add this styling when it recognises an email address.)

Equal opportunities


  • deaf people, not the deaf
  • people with disabilities, not disabled people
  • wheelchair users, not people in wheelchairs
  • people with AIDS, not AIDS victims
  • elderly people, not the elderly or old people
  • ethnic minority group/community or minority ethnic group/community, not ethnic group/community.

Figures and captions

Reports should reference Figure 1, Figure 2, Figure 3 (longer documents may group by chapter: Figure 1.1, Figure 1.2, Figure 2.1, Figure 2.2, etc.). Use sentence case for captions.

File naming

If you intend a file to be downloadable, use lowercase letters, and substitute spaces with dashes: chart-showing-migration-of-birds.pdf


Headings, headlines and subheadings take an initial capital only (ie they are in sentence case).

Headlines and links

News headlines in our magazines and web stories should use active verbs:

  • Cambridge professor discovers new technique
  • New technique for cell extraction discovered.

The headline of a webpage should always be the same as any links leading to it. Your page should not be called ‘Information for prospective students’ if the link to it is ‘How to apply’.

Keep headlines as short as possible.


When an adverb is used to qualify an adjective, if the adverb is not readily identifiable as an adverb, it should be hyphenated. For instance, in the phrase 'deep blue sea', 'deep' could be an adverb to indicate that the colour of the sea was both blue and of considerable depth. To demonstrate that 'deep' is being used to qualify the adjective 'blue', the phrase is hyphenated 'deep-blue sea'. 

Adverbs that end in 'ly' do not use hyphens eg slowly moving train, highly educated scholar.

We hyphenate compound adjectives when they appear before a noun (even when the noun itself is omitted for brevity eg A-level).

A hyphen is used to separate two vowels used together in a word when they are the same vowel, eg co-ordination, micro-organism, co-operate. Where vowels are different, we do not use a hyphen: it's 'reappointed' not 're-appointed'.

We do not hyphenate:

  • biomedical
  • email
  • fundraising
  • multidisciplinary
  • online
  • postdoctoral
  • spinouts
  • startups (in relation to companies)
  • website

We do hyphenate Co-ordinator, Vice-Chancellor and Pro-Vice-Chancellor.


Use italics for non-English words, book/journal titles (eg Charles Dickens’ Bleak House), sculpture, ships and titles of motion pictures, but keep song titles in roman without quotes: Symphony No 5 in C minor, A Hard Day’s Night. Note, we do not use italics for festivals, such as the Cambridge Festival and Open Cambridge, or lecture titles.


The style for species nomenclature should depend on the target audience for the document being published: 

  • Documents aimed at a lay audience should use uncapitalised common names, followed directly by the scientific name in italics (ie the scientific name should not be in parentheses) at a species’ first mention. Subsequent mentions of a species should use the common name rather than the scientific name. However, including scientific names in the main text may not be necessary if supporting documentation (eg an appendix) is provided with more detailed species information featuring scientific names as well as common names (see the Baseline Biodiversity Summary Report (PDF) for an example of this).  For more informal communications, such as news articles, the inclusion of the scientific name may not be necessary.  
  • Documents aimed at a more scientific audience, including expert naturalists, should use capitalised common names followed directly by the scientific name in italics (ie the scientific name should not be in parentheses) at a species’ first mention. Subsequent mentions of a species should use the capitalised common name rather than the scientific name (see the Biodiversity Action Plan (PDF) for an example of this).

Above all, the style of species nomenclature should be as consistent as possible within a document. Note that a single document may contain two different style ‘levels’ within it, eg the style in the appendix may differ from that in the main text, although the style should be consistent within each section. 

Any proper nouns in common names should always be capitalised even if the rest of the common name is uncapitalised, eg ‘Gooden’s nomad bee’ or ‘Himalayan balsam’.

Normal, universally recognised rules of using scientific names apply, including for species without common names, such as italicisation, capitalisation of the genus name, abbreviation of the genus name in subsequent mentions of a species, etc.  For example, use Poplar Populus Sp. / alliums and iris (exotics) / Verbena Spp. when aimed at a scientific audience and poplar Populus sp. / alliums and iris (exotics) / Verbena spp. when aimed at a non-scientific audience.

Log in

We use 'log in' to describe the action of a user entering their username and password on a University website (we do not refer to this as 'logging on'). The equivalent noun is 'login' (no space).


Avoid leaving a space between number and unit of measurement (10km, not 10 km). Commonly used measurements include: cm, mm, km, g, l (litre), MB, GB, kHz, MHz, KB. Follow the International System of Units (SI) as a guide for units of measurement. If your source material uses imperial units, always include the metric equivalent in brackets.

Names and initials

When referring to the Vice-Chancellor's full title we use: 

  • Vice-Chancellor Professor Stephen J Toope
  • University Vice-Chancellor Professor Stephen J Toope

Full points are not used after initials, eg Dr M P S Handley (with space between each initial).

No comma between a name and honorarium eg Dame Jane Goodall DBE.

When alphabetical lists of names are being given, follow a strict alphabetical order:

  • Mac appears before Mc de Sa,
  • du Plessis appears under D
  • Spanish names appear under the first family name, eg M Rangel Archila de Novais comes under Rangel.

Companies, countries and institutions should all be singular (AstraZeneca believes that…Cambridge United is having a good season…). Data should also be treated as singular.

Numbers up to and including ten are spelt out in letters – one, two and so on.  Subsequent numbers are shown as numbers, 11, 12 and so on. When a sentence starts with a number, it should be spelt out:

  • Thirty bridges were constructed and 150 villages benefited.
  • A hundred acres of woodland were enclosed, protecting more than 1,000 trees
  • 30 bridges were constructed and 150 villages benefited.
  • 100 acres of woodland.

Spell out million, billion wherever possible: one million, preceded by a space. Use figures when working with currency: £1 million and when quoting specific amounts.  Include the GBP equivalent of non-GBP currency amounts.

Avoid starting a sentence with a number, but if you must, then write as prose: Sixty-four students graduated, of whom 31 were from outside of the UK. (Alternative construction: In January 2013, 31 of the 64 students that graduated were from outside of the UK.) 

Note, in British English a billion used to be a million million (1,000,000,000,000) but is now aligned with the American billion (1,000,000,000). Numbers over a thousand should use a comma, eg 1,234 not 1234.

Fractions do not use a hyphen, eg two thirds, not two-thirds (but hyphenate if used as an adjective: a two-thirds majority).

Page references are always the shortest admissible within the range. For example, pages 34–5 or 46–54 or 107–17 or 136–8

See also: percentages

Numerical ranges

If working with a word-based description, then use from and to:

  • Children aged from 12 to 16.
  • Children aged from two to three.

Children aged 12–16 is also fine, but don’t mix use of the en dash with ‘to’ in the same sentence (avoid: Children aged from 12–16).

We use the 12-hour clock to express time. See time for more details.

Telephone numbers should be expressed on stationery as Telephone: +44 (0)1223 123456. Internal numbers as (3)12345.


Ensure one line space between paragraphs and do not indent the first line of a paragraph.

Keep paragraphs short, especially when writing for the web. Bear in mind that large blocks of text put readers off.

Past continuous and past simple

Past continuous should be used when describing something that was in the process of happening and past simple used when describing something that happened:

  • I was sitting on the train when the phone rang.
  • I was sat on the train when the phone rang.


When giving a percentage, always use % with a numeral, eg 3%, 8.8%, 100%. The word ‘percent’ should be reserved for discussing the concept, as in the following sentence:

  • Be alert to the different between percent and percentage points when discussing increases and decreases: if the higher tax rate increased from 40% to 48%, it would have increased by 20% (eight is 20% of 40) but by eight percentage points.


Drop initial capitals if referring to more than one heads of school (no s), deans of faculty (no s) as each head or dean is head of one school or dean of one faculty. This is in contrast when using someone’s job title: Head of Department, Professor Gerard Evan.

For the plural of Master, the apostrophe follows the s: Masters' regulations or Masters' degrees. For the singular of Master the apostrophe precedes the s: a master's degree in Computing Science.


Apostrophes indicate a missing letter or letters in an elision (where two or more words are run together), eg it’s (it is), aren’t (are not), I’ll (I will). They are also used for the possessive eg Tom’s lunch.  When a noun ends with an s and the final syllable is pronounced, the possessive s is added, eg Thomas’s lunch, Dr Huw Jones’s research, Octopus’s Garden.

Use single spaces after a full stop, not double spaces.

Commas (Oxford/Harvard) An Oxford comma is one used before an 'and' at the end of a list and is used to avoid ambiguity:

  • The family meal was soup, fish and chips, and ice cream. 
  • The jumper is available in green, yellow, and black and white.

A comma may also be used before an 'and' when two statements are linked:

  • Charlie has been learning the clarinet for 12 years, and today he is an accomplished member of the local orchestra.

Colons and semi-colons Use a colon before a list, a summary or a quote and to complete a statement of fact. Use a semi-colon to link two separate sentences that are closely connected and to separate points in a list that follows a colon and already contains commas. To illustrate how the semi-colon and colon can contribute to the sense of a sentence, here’s a nice example of correct usage from Sussex University.
Consider the two statements below. They have equal weight and may be unconnected.

  • Lisa is upset. Gus is having a nervous breakdown.

Now separate them by a semi-colon. They are now related or linked.

  • Lisa is upset; Gus is having a nervous breakdown.

Now substitute a colon:

  • Lisa is upset because Gus is having a nervous breakdown.
  • Lisa is upset: Gus is having a nervous breakdown.

Dashes Use shorter en-dashes (–) for dates such as 1995–96 and longer em-dashes (—) to represent a pause in text.

Quotation marks As we write in British English, we use single quotation marks for thoughts or reported quotations that are sourced from text. We use double quotation marks for speech (direct quotes). For example, a headline might say Gold's 'intrinsic' value questioned but within the text, if the article's author has interviewed someone and is reporting their words verbatim, you would see "I would not say that gold has an intrinsic value". Bear in mind that when using single quotation marks, quotes within quotes use double quote marks; this pattern is reversed for quotes within reported speech marks.

A full stop is used outside the quotation mark if the quote is only part of a sentence. (The scientists believed that there was a real need 'to get out of the office and into the field'.)  It is placed inside the quotation mark if the quote is a complete sentence.
When you break a quote into two paragraphs, you omit the closing speech marks at the end of the first paragraph and start the second paragraph with opening speech marks. Here is an example:

“…the rainforest was threatened by logging companies.
“However, the government is now taking action to halt illegal activities in this precious habitat...”

Single quotes also signify unfamiliar words or phrases. They should not be used for words which are well understood, eg real life and GM. 

Do not use end punctuation to close a pull-out quote.

Hyphens are used in words beginning with prefixes such as co, de, pre, or re when two of the same vowels appear together (co-operate, re-emerge, de-escalate, pre-eminent) but not when the vowels are different (proactive, reorder). They are used to join two word adjectives in order to make the sense: (clear, deep-blue sea, 19th-century history). Ages are hyphenated when used as adjectives (six-year-old children). When an age range is being described, use hyphens as follows:

  • five- to six-year-old girls
  • 16- to 19-year-old students
  • 18- to 24-year-olds. 

See also: hyphenation

Telephone numbers

  • For external audiences and on stationery use: Telephone: +44 (0)1223 339397.
  • For internal audiences use: Telephone: 39397.


Time is expressed following a 12-hour clock, using a full stop between the numbers and without full stops in am and pm: 12.45pm. Times on the hour are shown without the full stop and minutes: 8am.

Use am and pm when referring to time in the body of text:

  • Opening hours are 11.30am to 6pm.

Note within listings, or where space is tight, am and pm may not be needed:

  • Open Monday–Friday, 10–1 and 2–5, and Saturday 10–4.

When a male professor has been knighted he becomes Professor Sir Nicholas Shackleton and when a female professor is knighted she becomes Professor Dame Louise Johnson.  Once the full name has been given, subsequent mentions in text and quotes should be Sir Nicholas and Dame Louise.

For style guidance about job titles and degrees, see capital letters. For forms of address, see abbreviations.


University of Cambridge is the University's title and should be used in all communications and publications. To facilitate a good writing style, the word 'Cambridge' may well be a suitable substitute when faced with inconsistency. Cambridge University should be avoided where possible (although it is used in some proper nouns, eg Cambridge University Library and for many of our social media accounts).

When referring to the University alongside the University of Oxford the names should be written in full: the Universities of Oxford and Cambridge. The term Oxbridge should be avoided.

The University should be referred to as a singular: use has, is, etc.

Who and whom

Who is used for the subject of a sentence and whom for the object of a sentence:

  • The girl who gave me the apple had fair hair. 
  • The girl to whom I gave the apple had fair hair.
  • The man who spoke to me was in a rush.
  • The man with whom I was speaking was in a rush.

Who, that and which

Who refers to people; that and which refer to groups or things. That is used for restrictive clauses, which for non-restrictive clauses.

Which almost always follows a comma or a dash. 

  • Restrictive example: Houses that are old need a lot of maintenance.
  • Non-restrictive example: Houses, which have to withstand the weather, need a lot of maintenance.
