Forms

pidocchioso (feminine pidocchiosa, masculine plural pidocchiosi, feminine plural pidocchiose)[1] Old forms include Old Italian pedochiosa and Sicilian piduchiusu.[2] GDLI also records pedocchioso and pedochioso.[3]

Etymology

It is inherited from Late Latin peduculōsus (“lousy”), a Late Latin variant of classical pēdiculōsus, formed on pedŭculus (“louse”).[4][5][6][3][7] DEI finds it in the Latin glossaries and notes that the formation is shared by Italian, Romanian and Gallo-Romance.[8] Wiktionary gives a Vulgar Latin *peduclōsus as the intermediate form.[1] Sabatini–Coletti, Treccani and the TLIO see an Italian formation instead, by which it is from Italian pidocchio + -oso.[9][10][2]

The base noun is from Late Latin pedŭclus, the Late Latin contraction of that diminutive of pēdis (“louse”), whose origin DELI calls uncertain.[11][4] Nocentini connects it with the root Proto-Indo-European *pezd- of pēdō (“to break wind”), perhaps from the small crack a louse makes when it is crushed between the thumbnails.[4]

Earliest recorded meaning

The first record in the TLIO is the Sicilian glossary Declarus of Senisio, of 1348, where the word describes a body, especially a scalp, infested with lice.[2] DELI's first record is a Lucca document of 1357, from a collection of insults.[11]

Semantic evolution

From the start the word was strongly pejorative, suggesting dirt and deep poverty as well as lice.[3] Boiardo says of a king's followers that his people are tutta pedochiosa (“all lousy”).[3]

The figurative sense “stingy, mean” appears in Aretino in 1534, in a story of a master who tried out his servants for a month and then sent them away.[11] Michelangelo Buonarroti the Younger used it for “paltry” in 1618, and Fanfani recorded it for “miserly” in 1855, though Venetian peochioso already meant “miserly” in Boerio's dictionary of 1829.[11] A Tuscan proverb ran Mercante litigioso, o fallito o pidocchioso (“a quarrelsome merchant is either bankrupt or a pauper”).[12]

Modern Italian keeps the literal sense, the sense “wretchedly poor” and the sense “stingy”, the last two also as nouns.[5][10][13]
