ducks in a row

“to have one’s ducks in a row” is an idiom meaning to have all one’s preparations done or arranged before beginning an activity or project, and the phrase is thought to have arisen by allusion to a mother duck leading her ducklings in an orderly single file. In my original column I noted that the phrase was first attested in print in 1979, but it has since been found in a Washington Post article from 1932.–Word Detective
