Etymology

It is borrowed from Old French plege (“hostage, security, bail”),[2][3][4] probably from Frankish *plegan (“to guarantee”),[2][3] from a West Germanic root meaning to have responsibility for, seen in Old Saxon plegan, to vouch for (see play and plight).[3][2] Hoad and Merriam-Webster derive the French word instead from Late Latin plebium, security, from plebīre, to assure, of unknown origin.[4][5]

Earliest recorded meaning

A surety or bail, a person who stands as guarantee for another: 1348,[2] the mid-14th century in Etymonline; the surname Plegg is from 1284.[2][3]

Semantic evolution

Property given as security for a debt is from the late 15th century, in Caxton,[3] and a token of favour or agreement from the 1520s.[3][4] A vow sealed by drinking with someone is from the 1630s,[3] and the verb, to drink a toast, from the 1590s.[3] The sense of a solemn promise is first recorded only in 1814.[2][3][4] The verb, to give as security, to promise, is from about 1400.[2][3] In American colleges, a pledge is a student who has promised to join a fraternity or sorority.[6]
