Emily Dickinson Lexicon

WIGHT, n. [Sax. wiht, G. wicht, a living being, Goth. waiht; L. victum, from vivo, to live, originally vigo or vico, and probably allied to vigeo. This, in the Celtic form, would be quic or qwig, Eng. quick, alive; and hence L. qui, quæ, quid, quod, contracted from quic, quiced, quoced; Scot. quhat. The letter h, in the Gothic and Scotish, representing the c of the Latin, proves the word to be thus contracted.]

A being; a person. It is obsolete, except in irony or burlesque. [See Aught.] The wight of all the world who lov'd thee best. – Dryden.
