lieto

Forms

lieto (feminine lieta, masculine plural lieti, feminine plural liete, superlative lietissimo)^[1]

Etymology

It is inherited from Latin laetus (“glad, joyful; fertile, rich”).^[2][3][4][1] DELI and Nocentini explain that the Latin adjective first meant “fertile, fruitful”, a word of the farming world, and that this older sense lives on in letame “manure”; letizia comes from the same word.^[2][3][5] GDLI classes the Italian adjective as a learned word.^[6] The same word is Old French lié, Old Occitan let, Romansh led, Old Spanish ledo and Portuguese ledo.^[3][7]

The origin of the Latin word is unknown.^[1][3][8] Assuming that “fat, rich” is the older sense, Walde–Hofmann and Pokorny connect it with lardum (“bacon”) and largus (“generous”), but de Vaan calls this reconstruction very artificial.^[9][1] The OLD notes that it is unclear which sense is the original one, and that Cicero took “glad” to be the basic meaning.^[10]

Earliest recorded meaning

Nocentini dates the word to 1261 and Zingarelli to 1266.^[3][11] DELI's first record of the sense “bringing joy” is in Brunetto Latini, who died in 1294, and of “feeling or showing contentment” in Dante's Commedia (1300–1313).^[2][4]

Semantic evolution

Lorenzo de' Medici's carnival song gave the language a famous couplet: Chi vuol esser lieto, sia: / di doman non c'è certezza, “Let whoever wants to be happy be so: there is no certainty about tomorrow.”^[6][12] In literary Italian lieto is also said of places that delight the eye, as in Dante's Una montagna v'è che già fu lieta / d'acqua e di fronde, “There is a mountain there that once was glad with water and leaves”.^[13][12] The Latin farming sense survived in poetry for land and plants, “fertile, luxuriant”, from the 14th century to Tasso and Bembo.^[5][4][14]

Lieto evento, the birth of a child, is a 20th-century journalistic phrase, which DEI compares with English “happy event”.^[5] Lieto fine is a happy ending, and lieto di conoscerla is a polite formula for introductions.^[11][12]
