1787, from Scottish, where apparently it survived as an alteration of Middle English glenten "gleam, flash, glisten" (mid-15c.), from a Scandinavian source (compare Norwegian gletta "to look," dialectal Swedish glinta "to shine"), from Proto-Germanic *glent-, from PIE *ghel- (2) "to shine," with derivatives referring to bright materials and gold (see glass). Reintroduced into literary English by Burns. Related: Glinted; glinting.
