invest: [16] The etymological notion underlying invest is of ‘putting on clothes’. It comes via Old French investir from Latin investīre, a compound verb formed from the prefix in- and vestis ‘clothes’ (source of English vest, vestment, travesty, etc). It retained that original literal sense ‘clothe’ in English for several centuries, but now it survives only in its metaphorical descendant ‘instal in an office’ (as originally performed by clothing in special garments).

Its financial sense, first recorded in English in the early 17th century, is thought to have originated in Italian investire from the idea of dressing one’s capital up in different clothes by putting it into a particular business, stock, etc.

invest (v.)youdaoicibaDictYouDict
late 14c., "to clothe in the official robes of an office," from Latin investire "to clothe in, cover, surround," from in "in, into" (see in- (2)) + vestire "to dress, clothe" (see wear (v.)). The meaning "use money to produce profit" first attested 1610s in connection with the East Indies trade, and is probably a borrowing of Italian investire (13c.) from the same Latin root, via the notion of giving one's capital a new form. The military meaning "to besiege" is from c. 1600. Related: Invested; investing.
