Forms

rilassato (feminine rilassata, masculine plural rilassati, feminine plural rilassate)[1] Old forms are Old Italian relassato and the Latinizing relaxato.[2][3]

Etymology

It is the past participle of rilassare (“to relax, loosen”), used as an adjective.[4][5][6][1] The verb is a learned form of Latin relaxō (“to loosen; to relieve”), recorded as Old Italian relassare before 1342 in Domenico Cavalca and as rilassare in Florio's dictionary of 1598.[7][4] GRADIT treats it as a variant of rilasciare, the popular continuation of the same Latin verb.[8][4] The Latin verb is re- and laxō (“to loosen”), from laxus (“wide, loose”), which de Vaan derives from Proto-Indo-European *slǵ-so-.[9][1]

Earliest recorded meaning

Nocentini, Devoto–Oli and Sabatini–Coletti date the adjective to the 16th century.[4][5][6] The early examples in GDLI are medical: limbs weakened by hunger in Michelangelo Buonarroti the Younger, and stomachs rilassati in the physician Baldassare Pisanelli.[2]

Semantic evolution

In the 17th and 18th centuries the word described slack fibres, muscles and joints: Francesco Redi writes of vessels grown weak and relassate, and Anton Maria Salvini of the slack muscles of the eye.[2][3] Vasari used it for the patient, relaxed pose of a martyr in a painting.[3] The figurative sense “lax” was applied to morals and discipline: costumi rilassati.[5][6]

The sense “calm, free of nervous tension” is recent: DELI, quoting Carlo Tagliavini (1960), says that rilassare and rilassarsi took it from English relax.[7] In phonetics rilassato describes a sound made with little muscular tension, opposed to teso.[5][6][10]
