英语词汇allegro的起源、历史背景-英语词源词典

词汇	allegro
词源	allegro 1721 as a musical term, from Italian allegro "brisk, sprightly, cheerful," from Latin alacrem (nominative alacer) "lively, cheerful, brisk" (see alacrity). The same Latin word came into English 17c. as aleger "lively, brisk," from Old French alegre, from Latin alacris; and Milton used "L'Allegro" in its literal sense as a poem title (1632). Entries linking to allegro alacrity n. "liveliness, briskness," mid-15c., from Latin alacritatem (nominative alacritas) "liveliness, ardor, eagerness," from alacer (genitive alacris) "cheerful, brisk, lively;" a word of uncertain origin. Perhaps cognate with Gothic aljan "zeal," Old English ellen "courage, zeal, strength," Old High German ellian. But de Vaan suggests the root sense is "to wander, roam" and sees a possible connection with ambulare. allegretto 1740, in music, In music, indicating "quicker in time than andante, but not so quick as allegro;" from Italian allegretto, diminutive of allegro (q.v.) "brisk, sprightly." Also as a noun, a musical movement in such time. updated on September 17, 2022
