Etymology

Origin of ply¹

First recorded in 1350–1400; Middle English plien, shortened variant of ap(p)lien apply

Origin of ply²

First recorded in 1350–1400; Middle English verb plien, pleie, plaie “to bend, fold, mold,” from Middle French plier, ployer “to fold, bend,” variant of ployer, Old French pleier, from Latin plicāre “to fold”; see origin at fold ¹

Explanation

Ply means to work steadily at something. If you've got a lemonade stand and you're busy perfecting your recipe and seeking out customers, you're doing a good job of plying your trade. A ship that regularly travels a particular route plies that route. When someone offers you food or drink, often in hopes of getting something in return, they're plying you: "If I ply you with cake, will you take my dog for a walk?" The noun ply is very different from the verb, referring to layers or strands. Four-ply yarn is made up of four strands. Plywood is made of many layers of wood glued together.
