late 14c., grant “large, big” (early 12c. in surnames), from Anglo-French graunt and directly from Old French grant, grand (10c.) “large, tall; grown-up; great, powerful, important; strict, severe; extensive; numerous,” from Latin grandis “big, great; full, abundant,” also “full-grown;” figuratively “strong, powerful, weighty, severe” (perhaps cognate with Greek brenthyomai “to swagger, be haughty”). It supplanted magnus in Romanic languages; in English with a special sense of “imposing.” The connotations of “noble, sublime, lofty, dignified,” etc., were in Latin. As a general term of admiration, “magnificent, splendid,” from 1816. Related: Grander; grandest.
The use of grand- in compounds, with the sense of “a generation older than, or younger than,” is first attested c.1200, in Anglo-French graund dame “grandmother.” Latin and Greek had similar usages.
