There is an old saying that America and Britain are “two nations divided by a common language.”
No one knows exactly who said this, but it reflects the way many Brits feel about American English. My British friend still tells me, “You don’t speak English. You speak American.”
But are American and British English really so different?
Vocabulary
The most noticeable difference between American and British English is vocabulary. There are hundreds of everyday words that are different. For example, Brits call the front of a car the bonnet, while Americans call it the hood.
Americans go on vacation, while Brits go on holidays, or hols.
New Yorkers live in apartments; Londoners live in flats.
There are far more examples than we can talk about here. Fortunately, most Americans and Brits can usually guess the meaning through the context of a sentence.
Collective nouns
There are a few grammatical differences between the two varieties of English. Let’s start with collective nouns. We use collective nouns to refer to a group of individuals.
In American English, collective nouns are singular. For example, staff refers to a group of employees; band refers to a group of musicians; team refers to a group of athletes. Americans would say, “The band is good.”
But in British English, collective nouns can be singular or plural. You might hear someone from Britain say, “The team are playing tonight” or “The team is playing tonight.”
Auxiliary verbs
Another grammar difference between American and British English relates to auxiliary verbs. Auxiliary verbs, also known as helping verbs, are verbs that help form a grammatical function. They “help” the main verb by adding information about time, modality and voice.
Let’s look at the auxiliary verb shall. Brits sometimes use shall to express the future.
For example, “I shall go home now.” Americans know what shall means, but rarely use it in conversation. It seems very formal. Americans would probably use “I will go home now.”
In question form, a Brit might say, “Shall we go now?” while an American would probably say, “Should we go now?”
When Americans want to express a lack of obligation, they use the helping verb do with negative not followed by need. “You do not need to come to work today.” Brits drop the helping verb and contract not. “You needn’t come to work today.”
