gloam (n.)youdaoicibaDictYouDict
1821 (Keats, "La Belle Dame sans Merci"), a back-formation from gloaming that consciously or not revives the Old English noun.
quote (v.)youdaoicibaDictYouDict
late 14c., coten, "to mark (a book) with chapter numbers or marginal references," from Old French coter, from Medieval Latin quotare "distinguish by numbers, number chapters," from Latin quotus "which in order? what number (in sequence)?," from quot "how many," from PIE *kwo-ti-, from pronominal root *kwo- (see who).

The sense development is via "to give as a reference, to cite as an authority" (1570s) to "to copy out or repeat exact words" (1670s). Modern spelling with qu- is from early 15c. The business sense of "to state the price of a commodity" (1866) revives the etymological meaning. Related: Quoted; quoting.
threshold (n.)youdaoicibaDictYouDict
Old English þrescold, þærscwold, þerxold, etc., "door-sill, point of entering," of uncertain origin and probably much altered by folk-etymology. The first element probably is related to Old English þrescan (see thresh), either in its current sense of "thresh" or with its original sense of "tread, trample." Second element has been much transformed in all the Germanic languages, suggesting its literal sense was lost even in ancient times. In English it probably has been altered to conform to hold. Liberman (Oxford University Press blog, Feb. 11, 2015) revives an old theory that the second element is the Proto-Germanic instrumental suffix *-thlo and the original sense of threshold was a threshing area adjacent to the living area of a house. Cognates include Old Norse þreskjoldr, Swedish tröskel, Old High German driscufli, German dialectal drischaufel. Figurative use was in Old English.
