O.E. borgian "to lend, be surety for," from P.Gmc. *borg "pledge," from PIE *bhergh- "to hide, protect" (see bury). Sense shifted in O.E. to "borrow," apparently on the notion of collateral deposited as security for something borrowed. Cf. O.E. borg "pledge, security, bail, debt," O.N. borga "to become bail for, guarantee," M.Du. borghen "to protect, guarantee," O.H.G. boragen "to beware of," Ger. borgen "to borrow; to lend."
