Tired expression

OLDSAW

Think of a well-worn phrase that’s been around far too long.

"Tired expression" hints at a phrase that’s both overused and literally means "old." The answer plays on the idiom "old saw," where "saw" refers to a well-worn saying—not the tool. Think of it like calling a cliché an "old chestnut," but with a twist that fits the wordplay. The clue cleverly merges the idea of being tired (old) with a common expression (saw).
