Vocabulary is all the language and words either used or understood by a person or group of people. An example of vocabulary is all the words that a toddler understands. An example of vocabulary is the language used by doctors.
Introduction
The concept of adding milk to tea would offend many tea-loving Americans. On the other hand, the British have a reputation for adding milk to their tea. Even if tea and milk are more frequently enjoyed as a staple in Great Britain than in the United States, everyone may appreciate the traditions for what they are. Similar to that, the language used by Americans and Britons may be understood by both sets of speakers while being spoken differently in the two countries.
Vocabulary differences
There are certain terms that are used in both American and British English yet have different meanings. You wouldn't want to confuse a British geezer, who is generally a man of any age and is someone you could know or think is "cool," with an American geezer, who refers to an elderly person. Similar to how you wouldn't want to use the British equivalent of the word—homely, which means plain or ugly—to describe an American home (cozy, comfortable).
You'll also want to confirm that you're referring to the right football depending on where you are. Football is the term used to describe the sport in which a black-and-white ball is kicked across a field across Europe and much of the rest of the globe (Americans call this soccer). However, football is not popular in the United States.
Conclusion
It shouldn't come as a surprise that Americans speak more casually and directly than their British colleagues. Even in the workplace, Americans frequently say "hello" or "what's up?" to others. However, you are more likely to receive a "good morning" and a "how are you?" in Great Britain.
British idioms may communicate a sense of humour while still maintaining polite communication, even if they may sound foolish to Americans. Some Brits may conclude a list of straightforward instructions with "and Bob's your uncle." Other idioms between American and British English are obviously connected. While "odds and ends" may be used in American English, "bits and bobs" is more likely to be used in British English.
