A: Did you get the job you applied for?

B: Not yet, but it’s in the bag.

Note: This idiom means “virtually secured — as good as in one’s possession.” The expression alludes to the game bag in which hunters placed small game like birds and which was called simply “a bag” from about 1600 on. However, transferring this idea to a future success did not occur until the first half of the 20th century.
