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.
turn over: to sell retail; buy and then sell something to customers.
Example:
Wal-Mart has a quick turn-over on its goods.
heads will roll: threaten severe punishment.
Example:
The supervisor said that heads would roll if there were any further accidents with the forklift.
