rugginoso

Forms

rugginoso (feminine rugginosa, masculine plural rugginosi, feminine plural rugginose)^[1]

Etymology

It is inherited from Latin aerūginōsus (“covered with verdigris, rusty”), from aerūgō (“copper rust, verdigris”) with the suffix -ōsus.^[2][3][4][5] Zingarelli and Devoto add that the Latin word was reshaped after ruggine, the inherited outcome of the Latin noun.^[6][7] GRADIT treats it as formed from Italian ruggine + -oso within the language, and Wiktionary gives both explanations.^[8][1]

The Latin noun survives only in Italian, Romanian rugină and Lower Engadine ruìna; northern and southern Italian dialects also have a shortened base ⌜ruddza⌝, ⌜ruddzo⌝.^[9] The adjective lives on in the dialects, for example Ligurian rüzenùusu at San Remo.^[9]

Earliest recorded meaning

The first record is in the Novellino at the end of the 13th century, where a man hides “a rusty sword” (una spada rugginosa) under his furs: the sense is “covered with rust”.^[10][11][12]

Semantic evolution

Early writers used the word above all of iron and arms: Cavalca of a chain “very rusty and almost worn away”, Boccaccio and Ariosto of rusty armour.^[11] A proverb in Cavalca curses the iron that grows rustier the more it is filed and fired.^[13]

The colour sense “rust-coloured” is recorded from Leonardo da Vinci, before 1519.^[10] In literary use the word came to mean “neglected, out of practice”, as in Leopardi's “virtude rugginosa dell'itala natura”.^[3][14] It is also used of limbs stiff from long disuse and of plants affected by rust.^[15] Sericulture speaks of a bozzolo rugginoso, a silkworm cocoon with rust-coloured spots.^[14][6]
