Forms

folle m or f by sense (plural folli)[1] Old forms include Old Italian fol, Old Italian follo and Old Italian folo.[2]

Etymology

It is inherited from Latin follis (“leather bag, bellows; ball”), through its accusative.[3][4][5][1] The meaning passed by metaphor from a bag full of air or a ball to an empty head, and so to a fool.[3][4][6] DEI notes that the word was already used as an adjective in 6th-century France, in the “Life of Caesarius of Arles”.[7] Nocentini calls it a Romance formation from the Latin word, shared with French fou and Occitan fol;[4] Catalan foll belongs here too, and Spanish fol was borrowed from Occitan.[8][9][7] Zaccaria reported older proposals of a Germanic origin, such as a word for “full, drunk”, but the Latin etymology is accepted by all the modern dictionaries.[10][3][4]

The literal sense of the Latin word lives on in Spanish fuelle (“bellows”), Portuguese folle, Romanian foale, Sardinian foḍḍe and Venetian folo, from which come Italian folata and refolo.[4][9]

The Latin noun is related to flō (“to blow”) and has close comparisons in Old High German ballo (“ball”) and Old Norse bǫllr.[4][11] Wiktionary derives it from the root Proto-Indo-European *bʰelǵʰ- (“to swell”) or Proto-Indo-European *bʰel- (“to blow”); de Vaan compares only Celtic words and leaves the origin open.[1][12]

Earliest recorded meaning

The TLIO's first record is in the Venetian Proverbia que dicuntur of the late 12th century.[2] DELI's earliest dates are before 1249 in Pier della Vigna, of something done without sense, and before 1250 in Giacomo da Lentini, of a person who acts without reason, “mad”.[3]

Semantic evolution

In Old Italian folle meant mad from illness, but also rash, foolish, mad with love, insolent, and, of love, carnal or lustful.[2] Giovanni Villani writes of un folle e matto cavaliere who rose up in a time of turmoil, and an old proverb says chi folle invia, folle attende (“send a fool, expect a fool”), that errands should be given to the wise.[13] Derivatives appeared early: folleggiare in the early 13th century, follia before 1250, and folletto, a sprite, in Dante.[3]

In 1892 the word took on a mechanical sense: a part that turns idle without passing on the motion.[3][14] From it comes in folle, of a gearbox in neutral.[15][14] In colloquial speech folle also means huge or excessive, as in a prezzo folle.[5][6] Amare alla follia copies French aimer à la folie, criticized by Panzini in 1905.[3]

Usage notes

Folle is pronounced with an open o, and also with a closed one.[1][17] Several rarer words share the spelling: the archaic noun folle “bellows”, a learned borrowing of the same Latin word (Tasso compares the lung to mantice o folle),[4][5][18][15] the folle, a bronze coin of the late Roman Empire and Byzantium,[5][18][19] and folle bianca, a vine grape, from French folle-blanche (1956).[5][18]
