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.
fill the bill: be exactly what is needed
Example:
This new scheduling software should fill the bill for our advertisement sales staff.
bean-counter: accountant.
Example:
I’m so glad I don’t work in accounting. I can’t imagine being a bean-counter is very interesting.
