a, an

a historic or a heroic rather than an historic or an heroic

abbreviations

Try to avoid shortened words since they may not be understood outside the University: postgraduate certificate not PgCert

January not Jan. or Jan

UK not United Kingdom

USA or US not United States

EU not European Union

Eg, etc, ie are set in roman without full points

Do not use ampersands unless in a formal name or trade name: City & Guilds

Use per cent not % in text. Use the symbol in headlines, charts and figures

Close up unit abbreviations: 10mm, pp10–12

Close up am and pm: 5pm, 10am but 12 noon

Use Dr, Mr, Mrs, Ms, PhD, MSc, MA without full points

Spell out Professor in full: never use Prof. or Prof

Use the appropriate article (a, an, or the) with abbreviations when you would use that article in speech:The CII is part of the Department of Biology

accents

Use these where possible except in words that have become part of English: hotel, elite

accommodation has double c and double m

acknowledgement not acknowledgment

acronyms

Write the phrase or title in full the first time it appears, followed by the acronym in brackets. After that, you can use the acronym on its own.

Where the abbreviation is better known than what it stands for there is no need to spell it out in full: BBC, NATO, IRA, AIDS

Use:

• capitals, even if the acronym is pronounced as a word: AIDS, NATO, IPUP

Do not use:

• full stops in acronyms or put spaces between initials

addresses

printed

Use commas when the address is on one line: University of York, York, YO10 5DD.

If the address is on different lines do not use commas:

Department of Biology
University of York
York YO10 5DD

There is no need to include 'Heslington' in the University's address

For department addresses, put the department name before the University

Some important details:

• no full stops at the ends of the lines
• no comma between the number and the street name
• do not abbreviate Road, Street or Avenue
• postcode should appear after the town, county or city on the same line
• no comma between town/county and postcode

email

Try to avoid breaking email addresses in print if possible but not if a large amount of white space is left. Should you have to break an email address, break it at the @:

fred.bloggs
@york.ac.uk

Pay careful attention to capitalisation in email addresses.

website

There is no need to include http:// at the beginning of a web address, or a final forward slash. You can often leave out www.:

york.ac.uk

It is always a good idea to check any web addresses included in a publication before going to print.

In text, try to include a web address only at the end of a sentence. Do not insert space so it moves to start the next line. If it has to run over two lines, split it at a forward slash. Make web addresses consistently bold or italic and use a full stop (not bold or italic) as closing punctuation.

For very long addresses the Marketing team may provide a shortcut.

adviser not advisor

ageing not aging

Ages

Use initial capital letters in Dark Ages, Middle Ages, etc

A levels not A-Levels or A-levels

all right not alright

alumni (plural), alum (singular) not alumnus/alumna

amid, among not amidst, amongst

Bachelors not Bachelor's or bachelors

-based

Use with a hyphen when combined with another word to form an adjective: work-based study

benefitted, benefitting not benefited, benefiting

between and among

Use between with two people or things and among with three or more people or things

billion(s)

Use numerals followed by the abbreviation bn: £2bn

brackets

Punctuation stays outside the brackets (parentheses) if the sentence is complete without the information inside. (A complete sentence that stands alone in brackets starts with a capital letter and ends with a stop.)

Britain

Britain is a contraction of Great Britain and not the same as UK, but all can be used interchangeably in more colloquial contexts. Great Britain refers only to England, Wales and Scotland, UK includes Northern Ireland

Take care not to write Britain when you might mean only England and Wales, for example when referring to the education system. Use UK in the University of York address, not England

bullet points

Simple lists

Learners should identify the following organs of the human body:

• brain
• heart
• lungs
• stomach

Note there are no initial capital letters (unless using proper nouns) and no punctuation.

Part sentences

Sentences that have been broken down into bullet points should still 'flow' throughout:

People go on holiday to:

• have a change of scenery
• enjoy hot weather
• get away from editing BTEC Short Courses.

Note the colon, the lack of capitalisation and the single full stop. There is no need to end list items with a semicolon.

Full sentences

Bulleted lists containing complete sentences should start with a capital letter and finish with a full stop.

Students must give examples of how this is implemented.

• For mark band 1, one example is required of its implementation by either a care worker or the organisation.
• For mark band 2, more than one example of either a care worker or the organisation is required.
• For mark band 3, it is desirable that students give examples of both workers and the organisation.

There does not have to be a colon at the end of the preceding sentence.

Lists of links or headings

Bulleted lists are a convenient way of displaying links online. These usually act as headings, so should start with a capital.

Related links:

• Fees and funding
• Applying to study at York
• York graduates' discount

Campus East, Campus West not Heslington East, Heslington West

capital letters

Also known as u/c, or upper case

Capitalise:

• names of people, places and organisations (proper nouns)
• department names and degree titles, but not academic subjects in general
• names of institutions

• British government departments of state and agencies
• the main words in the names of programmes and modules within text
• months and days of the week
• countries, rivers, lakes and mountains
• job titles when referring to a person's specific title: John Smith, Vice-Chancellor, but Craig David, artist

Do not capitalise:

• the smaller words in titles such as in, at, of, the, and, on
• generic job or occupation titles: Most departments have lecturers and senior lecturers.
• general subject titles: Students study all aspects of archaeology.

University: use an initial capital in specific references to York: the University. When referring to a university or universities in general, use lower case.

College: use an initial capital when referring to a specific college: The College is named after Lord James. When referring to colleges in general use lower case: Goodricke is the first college on Campus East.

Avoid over-use of capitals as they make the text more difficult to read. Whole titles or chunks of text written in capitals should be avoided as it looks like YOU ARE SHOUTING at the reader. If you want to emphasise a word, use italic or bold instead.

Accents are not needed on capital letters.

city of York not City of York when referring generally to the city; use l/c for city

City of York Council is the full name of the Council

collective nouns

Nouns such as committee, family, government take a singular verb or pronoun when thought of as a single unit, but a plural verb or pronoun when thought of as a collection of individuals: The family can trace its history back to the Middle Ages.; The family were sitting down, scratching their heads.

colons (:)

Use colons to:

• introduce a list
• separate statements in a sentence, when the second statement explains the first

Never follow a colon with a dash (:-) or a capital letter unless the next word is a proper noun or title

combatted, combatting not combated, combating

compass points

Regional phrases should be in caps as in the North, the South, the West, the South East, etc but southeast England (because southeast is an adjective)

Use capitals for abbreviated compass points: NE, SW

CAT scan not Cat scan

church

Capitalise when referring to the body of the Catholic Church, but church when referring to the building

computer terms

Use the following spellings:

app
database

contact details

Always provide a telephone number and an email address

Telephone numbers should always follow the format: +44 (0)1904 32XXXX

There is no need to introduce contact details with the terms Telephone, Email or Web. They are self-explanatory

contractions

Contracted words, for example you'll for you will and we'll for we will, are fine in the right context. When writing for a student/prospective student audience, contractions can help establish a friendly, informal tone

course titles

University degree courses can be referred to as programmes or courses, but courses is preferred as it's more widely understood. The right way to write a course title is BA (Honours) History or BA (Hons) History

cooperate not co-operate

degree classes

First, 2:1, 2:2, 3rd. Never use 1st. Use a capital when referring to a First, but lower case initial for first-class degree. Never use first degree, as this can be confused with an undergraduate degree. She was awarded a First in biology. He was awarded a 2:1 in English. She was awarded a first-class degree in chemistry

departments

For all University departments always use Department of not XXX Department

Department has a capital D when it is part of the department's title: Welcome to the Department of Computer Science
