Forms

rilasciare (first-person singular present rilàscio, first-person singular past historic rilasciài, past participle rilasciàto, auxiliary avére)[1] Old forms include relassare, relaxare, relasciare and rilassare.[2]

Etymology

It is inherited from Latin relaxō (“to loosen, release; to relieve”), reshaped after lasciare (“to leave, let go”).[3][4][5][2] The Latin verb is formed from laxō (“to loosen, slacken”) with the prefix re- (“back, again”).[4][1][6] Sabatini–Coletti calls the verb the popular word beside the learned rilassare, from the same Latin verb.[7][4][8]

Some dictionaries explain the sense “to leave again” as formed anew in Italian, from Italian ri- + lasciare;[9][7][10] GRADIT dates that sense from 1598 and lists it under a separate heading.[9][7][10] Wiktionary takes the whole verb from ri- and lasciare, with the sense “to relax” borrowed from Latin.[1] Treccani attributes the sense “to put a new product on the market” to English release.[11]

Earliest recorded meaning

The first record is in the statute of the Wool Guild of Siena of 1298–1309, in the sense “to set free”: no outlaw may be relassato, released from his ban, before he has paid his creditor.[3][2]

Semantic evolution

The Lives of the Desert Fathers, in the 14th century, use the verb for loosening or relaxing, and the old language also had “to forgive, remit” and “to give up”, both now obsolete.[3][12][9] The sense “to leave again” is recorded in Perugian documents of 1410.[3]

The office sense “to issue, hand over” a document appears in Lorenzo Magalotti before 1712;[3][4][9] Tommaseo and Bellini still condemned it in 1872 as improper, but it is now the commonest use, together with rilasciare un'intervista, “to give an interview”.[3][4][9] In medicine and physiology it is used for relaxing muscles and for glands or cells releasing hormones or neurotransmitters.[9][10] The reflexive rilasciarsi “to split up again”, of a couple, is recorded from 1959.[3][12]
