Making the specific question more general: There's a point at which a phrase is just so... accurate that it just... is, you know? And maybe then it's beyond cliché? But on the other hand, anything overused becomes cliché... I guess... So where is the line drawn? If I have to ask "Is it a cliché?" then it probably IS, huh? Or is it?
CuriousGeorge/Clichés? Is it possible to use a phrase like "shadows lengthen" or "shadows creep" in a short poem (in which every word counts, unlike prose where there's sometimes more leeway) without sounding cliché? [MI]
