Editing in British English

A guide to the differences between American and British English

Editing in British EnglishEnglish can be a strange and confusing language. Its spelling and grammar rules aren’t always intuitive, and the fact that there are different varieties of English—British, American, Canadian, and Australian—makes things that much more perplexing . . . or so it seems. Today, we’re going to be looking at the main differences between the two most common varieties of English—British and American—and what to watch out for when editing in British English. Although the two aren’t that different, their variations in grammar—including spelling, usage, and punctuation—are still quite significant.

By comparing British English to American English, this article will list the most common things to watch out for when editing in British English. We will cover the topic of British English grammar as a whole, including spelling, usage, and punctuation, as well as the differences between American and British English. By the time you’re done reading this article, you’ll know exactly what to pay special attention to when editing in British English. Chocks away!

British English

British English is the variety of English spoken and written throughout the United Kingdom. Although British English has regional varieties, we’re going to keep it simple here by taking a broad approach and examining the main features of British spelling, grammar, vocabulary, usage, and punctuation. Learning these basics will provide you with a great knowledge base that you’ll find especially helpful when writing or editing in British English.

Let’s start with the main differences between American and British English, which include spelling, usage, and punctuation.

1. Spelling

The spelling of English words has not always been standardized. With the publication of influential dictionaries in the eighteenth and nineteenth centuries, spelling standards became increasingly common, although with differences between countries. These variances occurred for cultural, political, and linguistic reasons, and over the years, the differences have become more cemented (though never completely so).

The primary differences are between British and American spellings. American spelling conventions changed early on, and the variances have persisted throughout the years. Countries in the British Commonwealth (and Ireland) tend to follow British usage, although there are still some minor variations (Australian spellings, for instance, sometimes diverge from the British forms). The one major exception is Canada. Canadian English is more of a hybrid and follows typical British usage in many ways, while adopting certain common practices from its neighbor to the south.

Here are some of the main spelling differences between American and British English:

  • Words that end in –our in British English tend to end in –or in American English, but only when the –our ending is not stressed, such as in flav-our.
  • When the –our ending is stressed, however, the –our spelling is retained in American English, such as in vel-our.
  • Words ending in –erior are spelled this way everywhere, regardless of location.
    • superior
    • exterior
    • interior
    • inferior
  • Many words in British English end in –er, especially Germanic and Romance words. However, certain words with French, Latin, and Greek origins end in –re in British English. These –re endings are often not used in American English (e.g., theatre in British English is spelled theater in American English). Here are some other examples of -re endings in British English:
    • centre
    • metre
    • fibre
    • sabre
  • Many English words derived from Greek words end in –ize or –ise. The ending choice varies between, and often within, countries. Great Britain uses both –ize and –ise, although the –ise ending is more common.
  • For such Greek-derived words, the British usage is inconsistent. The –ise is more common, but the Oxford University Press and the Oxford English Dictionary, for example, use the –ize. The Cambridge University Press, on the other hand, adopts the –ise ending, and this is what is typically used in the British mass media for words such as criticise or organise.
  • Some words ending in –ize/-ise are not derived from Greek, and their endings are thus not interchangeable in British English. Examples include:
    • size
    • prize
    • seize
  • The use of the –yze or the –yse ending varies between countries. The –yse ending is used in British English, while the –yze ending is used in both American and Canadian English for words such as analyze.
  • Some words can end in either –ogue or –og, although the –ogue ending tends to dominate in all countries. Examples:
    • pedagogue
    • monologue
    • synagogue
  • In British English (and that of most Commonwealth countries), some words use either the ae or the oe combination, while in American and Canadian English, these are almost always reduced to a simple e. However, there are certain exceptions. The word fetus, based on etymology, should always be spelled fetus, but Britons often adopt the oe spelling, and the word becomes foetus. Academic journals everywhere tend to prefer the etymologically correct spelling, fetus.
  • A few words always (or usually) retain the ae or oe construction, even in American English:
    • phoenix
    • subpoena
    • toe
  • Latin –ae plural endings are not changed in any variety of English, as with the following:
    • larvae
    • formulae
    • antennae

Spelling Differences: Double Consonants in British English

How to Edit in British EnglishWhen adding a suffix that begins with a vowel, the final consonant is often doubled. This helps avoid confusion. For example, if you have tap and do not double the consonant p when adding the suffix –ed, you will end up with taped, which is the past tense of the verb tape. Doubling the consonant creates the word tapped instead.

Generally, this only occurs when the word ends with a single consonant following a single vowel and when the final syllable is stressed. However, in British English, a final –l is often doubled to –ll, even when the ending is unstressed. In American English, only one –l is used. Canadian English follows British usage here, typically using the –ll.

This doubling in British English is generally true for any such words ending in –ed, –ing, –er, –est, and -or, for example:

  • counsellor
  • counselling
  • counselled

However, for words ending with –ise/-ize, –ism, –ist, and –ish, the final –l is generally not doubled, as with the following:

  • novelist
  • sensualist
  • normalise

In words with other endings, such as –ous, –ee, and –age, the usage varies, with some doubled (marvellous) and others not (scandalous). Jewellery has –ll in British English but is spelled jewelry in American English.

Single –l endings are used if there is a double vowel.

  • foal (oa) becomes foaling
  • fool (oo) becomes fooling
  • pool (oo) becomes pooling

Single –l endings are used if there is a consonant preceding the final consonant.

  • bowl (w before the l) becomes bowling
  • whirl (r before the l) becomes whirling


The biggest differences between American English and British English are words with the following combinations: –our versus –or, –re versus –er, –ize versus –ise, –yze versus –yse, –ogue versus –og, and words with ae in American English that are spelled with oe in the British equivalent.

2. Usage

Usage refers to language etiquette and how words are commonly used (written and spoken). It also refers to using the right word in the right context. In terms of British versus American English, usage is where you’ll see the most obvious distinctions. Different words may be used for different reasons: convention, simplicity, socio-cultural reasons, and even aesthetics. There are too many examples to include here, but check out for a very thorough list.

Differences between American English and British English are probably the most noticeable in spoken language, but along with spelling and usage, there are also slight differences when it comes to British punctuation. The most important British punctuation rules to remember are:

  • The serial comma is not used. Example: I bought flowers, a vase and a card.
  • Single quotation marks (instead of double quotation marks) are used for initial quotations. For quotations within initial quotations, double quotation marks are used.
  • Punctuation (commas, periods) goes outside the quotation marks.
  • When writing titles such as “Dr.” or “Mr.,” the periods are omitted (“Dr” or “Mr”).
  • When writing times, British English uses a period between the hours and minutes (e.g., 4.30 p.m.), whereas American English uses a colon (e.g., 4:30 p.m.).
