final: [14] Of all the English descendants of Latin finis ‘final moment, end’ or ‘limit’ (see FINANCE, FINE, and FINISH), final, which comes via Old French final from Latin finālis ‘last’, preserves most closely the meaning of its source. But although by classical times finis denoted a temporal conclusion, its original use was for a physical boundary, and it appears to be related to figere ‘fix’ (source of English fix) – as if its underlying meaning were ‘fixed mark’.
