Forms
guastare (first-person singular present guàsto, first-person singular past historic guastài, past participle guastàto, auxiliary avére)[1] Old Italian also had vastare, with the Latin consonant.[2][3] Old forms with ⟨g⟩ alone, such as Old Italian gasto, are found beside Old Italian ghuastare.[4]
Etymology
It is inherited from Latin vastō (“to lay waste”), derived from vastus (“empty, desolate”).[2][5][6][1] The initial /gw/ for Latin /w/ is the treatment of Germanic words such as guado and guaina.[5][7][8] DELI, DEI and Wiktionary explain it by crossing with a Germanic word of the same root, Frankish *wōstijan (“to lay waste”) (Old High German wuosti (“desert”), modern wüst).[2][9][1][10] Nocentini doubts the identification, because the Germanic word has /oː/ where the Romance word has /a/.[5] Rohlfs counts the word among the few in which Latin /w/ was treated like Germanic /w/.[11]
The same verb is French gâter, and Occitan gastar, Catalan gastar, Spanish gastar and Portuguese gastar.[5][10]
De Vaan reconstructs Proto-Italic *wāsto- and PIE *h₁u(e)h₂-sto- for the adjective, and notes that the length of the vowel is uncertain.[12]
Earliest recorded meaning
The TLIO's first record is in the Venetian Proverbia que dicuntur, of the late 12th century, for damaging a thing so that it is no longer whole or sound.[4] The Latin-looking vastare appears in the 13th century in Inghilfredi and the Miracole de Roma;[2] DELI's first guastare, in Restoro d'Arezzo (1282), means “to reduce to a bad state”.[2]
Semantic evolution
In Old Italian the verb meant to lay waste a country or a town, as in Bono Giamboni before 1292, and the noun guasto the devastation; to mutilate (Dante); and in Boccaccio to corrupt.[2][11][13] The military guastatore, who destroyed fortifications, is in Malispini and was revived in the Second World War.[2]
Later uses are more domestic: food that goes off (Giovanni Villani), things that break, a mood or a friendship spoiled; in 1939–40 Palazzi records the sense of unpicking a garment to make it again.[2][6] The old senses “to destroy” and “to put to death” are now obsolete.[13][1] Phrases include guastare la festa, the source of guastafeste “spoilsport” (1618), and non guasta “it does no harm”.[2][6]
