Forms

ridurre (first-person singular present ridùco, first-person singular past historic ridùssi, past participle ridótto, first-person singular imperfect riducévo, auxiliary avére)[1]

Etymology

It is inherited from Latin redūcō (“to lead back”), formed from re- (“back”) and dūcō (“to lead”).[2][3][4][1] The Latin verb also meant “to give a form to, reduce”.[3] Its infinitive lost the inner vowel, as in condurre and indurre, and joined the infinitives ending in ⟨-rre⟩ such as trarre.[5] Older forms are Old Italian riducere, Old Italian reducere and Old Italian redurre, and Old Italian redugere in a 13th-century Genoese text.[2][6]

The same word is French réduire, Occitan reduire, Spanish reducir, Portuguese reduzir and Romanian arăduce.[3][7] The verb for “to lead” goes back to Proto-Indo-European *deuk- (“to draw”).[8]

Earliest recorded meaning

The Anonimo Genovese has redugere in the 13th century, and Dante reducere (1300–1313); the form ridurre is first in Giovanni Villani, before 1348.[2] The first sense is “to bring back to the starting point or to the proper place”, often figurative.[2][9]

Semantic evolution

Boccaccio, before 1375, uses the verb for making something smaller or shorter, now the main sense, and in 1348–53 for forcing someone to act in a certain way.[2] The reflexive ridursi “to take refuge” is in Villani, and “to fall into a worse state” in Sercambi (before 1424).[2] Technical senses followed: in chemistry before 1537 (Biringuccio), in mathematics before 1572 (Cosimo Bartoli).[2]

The sense “to take refuge, gather” lies behind the noun ridotto, a gathering place, a gaming house, and since Pietro Chiari (1771) the foyer of a theatre.[2][10]
