Every Saturday I’ll give you a couple of idioms to learn. An idiom is a saying or phrase whose meaning cannot be taken from the literal meanings of the words. Currently, we’re looking at some common English idioms.
drop someone a line: write a brief note / letter
Example:
Jack promised his grandmother he would drop her a line once he got settled at university.
figure something out: solve a problem, understand something
Example:
Have you figured out how to use that new software yet?
