British English and American English: Grammar and Usage Differences

In grammar and syntax, the American English (AmE) and the British English (BrE) are very similar. Not least because the influence of the American English on the British English is constantly growing—through films, television, pop music, the internet, and so on. It is probably safe to expect that even the contrasts shown here are likely, if not to disappear, at least to diminish in importance.

Examples of the main differences between the two variants are listed below. It should be noted that, in many of the following cases, two (or more) different forms are possible in one variety of English, with the first one being the most common.

Irregular Verbs

A number of verbs can be either regular or irregular in the Past Simple. However, in the United States and in the United Kingdom, the forms most commonly used are not the same. Generally speaking, the regular form is usually preferred in AmE, whereas the irregular form tends to be preserved in BrE:


fit vs. fitted

The verbs fit, quit, and wet are regular in BrE—but not in AmE. In the case of quit and wet, however, American usage is now well on its way to replacing British:


have gotten vs. have got/got vs. has got

In AmE, the past participle of get is either gotten or got, except in the structure have got, used as an alternative to have, which is the same as in BrE:


Past Simple vs. Present Perfect Tenses

In AmE, these two tenses are often interchangeable in conditions where only the Present Perfect can be used in BrE. For instance, when an action in the past has a result now (as in the first example below), the Present Perfect is normally employed.

Other typical cases are with words like just, already, and yet, as well as with ever and never referring to a period of time that continues until now:


Auxiliary & Modal Verbs: will vs. shall

In BrE, shall and its contracted negative shan’t can be substituted by will, indicating the future, when used with the pronouns I and we. In the U.S. English, shall is unusual, except for legal documents. Where shall is used in BrE to ask for advice, should is employed in the United States:


Verbs of Perception

In both varieties of English, it is possible to use can and could with verbs of perception, i.e., see, hear, feel, smell, and taste, but this practice is much more common in BrE:


don't need to vs. needn't

In BrE, needn’t is often substituted for don’t need to. However, in the U.S., the use of needn’t is unusual:


Subjunctive Constructions

In subjunctive constructions, after such verbs as suggest, recommend, demand, insist, etc., should is often used in BrE. In AmE, this is unusual:


Do as a Substitute Verb

In BrE, but not AmE, do can be used alone as a substitute verb after an auxiliary verb. In such cases, the auxiliary verb is stressed:


Have vs. Take

In a small number of expressions, BrE prefers have to the U.S. English take:


Position of Adverbs

Certain adverbs, known as mid-position adverbs (sometimes, always, never, often, definitely, certainly, etc.) are usually placed after auxiliary verbs and before other verbs: e.g., He has certainly done it.

However, when we wish to emphasize the auxiliary verb, we put most mid-position adverbs before it instead of after: He certainly has done it. In BrE, this second construction is always emphatic.

In AmE, however, the adverb is frequently placed before the auxiliary, even when there is no intent to emphasize:


Use of Real as an Intensifier

In informal AmE, real is often used before adjectives and adverbs where BrE insists on really:


Collective Nouns

In BrE, collective nouns like government, staff, committee, company, firm, audience, family, team, etc., can take either a singular or a plural verb. In AmE, such nouns usually take a singular verb. The same is true of certain proper nouns: for example, the names of countries or companies.



The use of prepositions occasionally varies, especially in adverbial expressions. When a preposition is used in one variety of English but not in the other, this is signified by (-). Here are some well-known examples:


Use of One

The pronoun one, used to talk about people in general, including the speaker and the listener, is much less used in the United States than in the United Kingdom.

When it is used in AmE, however, he, him, and his are generally used later in a sentence to refer back to it, where BrE would continue to use one or the possessive one’s.


Other Grammatical and Usage Differences

  • Hyphens: Hyphens are often used in BrE to connect prefixes with the main word: e.g., pre-emption, pre-trial, co-operation. They are less common in AmE: e.g., preemption, pretrial, cooperation.

  • Suffixes -eable/-able: The silent -e-, produced when forming some adjectives with a suffix is generally used in BrE in such words as likeable, unshakeable, and ageing. In AmE, it is generally left out: likable, unshakable, and aging. The -e- is, however, sometimes used in AmE where it affects the sound of the preceding consonant: traceable or manageable.

  • Directional suffix -ward(s): British forwards, towards, rightwards, etc., contrasts with American forward, toward, rightward.

  • While or whilst: Both while and whilst are used in BrE. In AmE, while is the right word to use, and whilst is regarded as a pretentious affectation.

  • Spelling a word aloud: When spelling a word aloud that has two consecutive identical letters, most Britons will use the word double. For example, to spell canned, Britons will say “c-a-double n-e-d.” Most Americans, however, will pronounce each letter separately: “c-a-n-n-e-d.”
