Etymology 1

From Middle English signe, sygne, syng, seine, sine, syne, from Old English seġn (“sign; mark; token”) and Old French signe, seing (“sign; mark; signature”); both from Latin signum (“a mark; sign; token”); root uncertain. Doublet of signum. Partially displaced native token.

Etymology 2

From Middle English signen, seinen, seinien, partly from Old English seġnian (“to mark; sign”) and partly from Anglo-Norman seigner, seiner et al., Old French signer et al., and their source Latin signāre (“to mark, seal, indicate, signify”); all from Latin signum (“a mark, sign”); see Etymology 1, above. Compare sain.
