A small piece or curl of hair; a thin, delicate hair or something resembling a small hair.
From Old English 'hær' (hair) + '-let' (diminutive suffix, from Old French, meaning small). The '-let' suffix creates small versions of things.
Diminutive suffixes like '-let' are fascinating because they let speakers be affectionate or specific—a 'hairlet' suggests something tiny and perhaps delicate, whereas just 'hair' is neutral and general.
