A
Most people already know some of the more obvious(明显的)differences between British and American English.American English leaves out the “u” in colour，neighbour，honour，etc.Most people also know that a lot of words mean different things in them: a boot is the trunk of your car，a jumper is a sweater，and thongs are flipflops.But there are some subtle differences between the two that you might not have noticed at first sight.
This is by no means a list of differences between the two.However，with British TV shows on American screens and vice versa(反之亦然)，not to mention their interaction(相互影响)we're able to see on the Internet，it's possible that some British or American words have come into each other's vocabulary，so some differences are starting to disappear.
First，speakers of British and American English have different preposition preferences.These little words are so small that you might not have noticed the differences when talking to your British or American friends.Each example is grammatically correct，but one or the other might sound a little strange to you depending on where you're from：British English: I will come home at the weekend.American English: I will see her on the weekend.
Second，there are a lot of differences in regular and irregular verbs in British and American English.That means that we add various endings on some verbs in one dialect that we don't in the other，but people can accept both of them.A couple of the verbs that are irregular in British English are burn，learn，and smell.These words are all regular in American English.For example：BE：She burnt the toast.AE：She burned the toast.
There are also a couple of verbs that are irregular in American English but are regular in British English，including dive，fit，and wet.For example:
BE: She dived into the lake.
AE: She dove into the lake.
There are other differences between British and American English.Both of them have developed over time，and they have a deep influence upon each other.
