Forms

decadere (first-person singular present decàdo, first-person singular past historic decàddi, past participle decadùto, first-person singular future decadrò, auxiliary èssere)[1] The early texts also have Old Italian descadere and Old Italian decazer in Milan.[2][3][4] Older dictionaries record Old Italian dicadere.[5][6]

Etymology

It is inherited from Vulgar Latin *dēcadere, a remaking on cadere of Latin dēcidō (“to fall down”), from dē- (“down”) and cadō (“to fall”).[2][7][1] The remade verb is recorded in Late Latin, in Chiron in the 4th century and in Isidore before 630.[8] Like the simple verb it had two forms, one stressed on the stem and one in long ⟨-ēre⟩.[8][4] Nocentini and Zingarelli start from the second.[7][5]

The same verb is French déchoir, Old Occitan decazer, Catalan decaure, Spanish decaer and Portuguese decair.[7][9][10] The LEI places the Catalan and northern Italian forms under the type stressed on the stem, and the French, Occitan, Spanish and Old Portuguese ones under the type in ⟨-ēre⟩.[8] The Latin simple verb goes back to Proto-Italic *kad-e/o-, and de Vaan reconstructs a PIE root meaning “to fall” only with a question mark.[11]

DELI finds the formation clear but the history obscure in its details: the family may have started from French décadence (1413, Medieval Latin decadentia), and the early descadere and descaduto would then be independent formations.[2] Zingarelli calls the word learned, and Devoto describes it as a cross of the Latin verb with the Italian simple verb.[5][12] decadenza and decadente are French loans, the second from décadent (1516).[8][2][8]

Earliest recorded meaning

The first record is Milanese decazer in Bonvesin de la Riva, before 1315, said of a plant that withers and loses its vigour.[3][8] Nocentini dates the verb before 1292, with the sense “to decline”.[7]

Semantic evolution

In Old Italian the verb meant passing from a good state to a bad one, and also becoming unhappy, a land going to ruin, simply falling, and an inheritance or right passing to someone.[3] A Roman text of about 1358 uses decadere a of a kingdom that falls to its heir.[8] Giovanni Querini's descadere in the 14th century has the main modern sense, said of poetry fallen from honour, and the form decadere follows before 1609 in Giulio Cesare Croce.[2][4]

The legal sense of losing a right, an office or a throne appears in Bandello in 1554, and decadere da from 1572.[2][8] The noun decadenza followed in Paolo Sarpi (1607–1618), and its legal sense of the extinction of an unexercised right in 1793.[2] In the 20th century the noun decadimento took the sense of radioactive decay (1965), and the verb is used of a radioactive substance that decays.[2][13][14]

At the end of the 19th century French décadent, which Théophile Gautier used in 1868 of Baudelaire's poetry, gave Italian decadente (1896) and decadentismo (1897), the name of the literary movement.[2]
