[speaker001:] Are there many idioms in English?
[speaker002:] There are hundreds and hundreds. English is particularly rich in idiomatic expressions.
[speaker001:] Can you give us an example?
[speaker002:] I'll look up the rate. To look up doesn't mean to look high into the sky or to look at the roof. It means to search for and find some information.
[speaker001:] What about the expression Goodbye? Is that an idiom?
[speaker002:] That is just a natural, grammatical English expression. It has a direct translation in other languages.
[speaker001:] This is interesting, Ms.Parker.
