Words like half (and similarly, calf) are difficult for Brits to say in an American accent, mainly because the 'a' sound is so vastly different from what they are used to. So instead of saying HAAHF, they should be pronouncing it HAY-AHF
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.
American English words missing from British English
Early British Americans had to acquire and use new phrases since they interacted with Native Americans and immigrants from other nations. Words changed in popularity in Britain in the meanwhile, but their American counterparts were unaware of this. In four hundred years, there will undoubtedly be many distinctions between the two dialects.
S'mores and grits may be American favourites, but black pudding, a traditional British breakfast sausage made of pork, pig's blood, and suet, may not be. Conversely, they can prefer eating pasties (pies filled with meat).
Because many of the phrases were developed from the changing British culture, it can be particularly challenging to translate them from British English to American English. Sixes and sevens, which originally referred to the order of the companies in the London Livery Company, have evolved to indicate "muddled" in everyday speech.
As science and technology developed, new terms were also created. Americans started filling their automobiles with gasoline once the automobile was invented in the 20th century, whereas Britons started filling theirs with petrol.
S'mores and grits are two uniquely American foods that lack British analogues.
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.
