Forms

relaxātiō f (genitive relaxātiōnis); third declension[1]

Etymology

It is from Latin relaxō (“to loosen, relax”) + -tiō.[2][3][1] De Vaan lists relaxō among the derivatives of laxus (“spacious, wide, loose”), which goes back to Proto-Italic *(s)lakso- and Proto-Indo-European *slǵ-so- (“weak, faint”).[4]

Earliest recorded meaning

Cicero has it, in a figurative sense: in the De oratore the fruit of leisure is not straining the mind but its relaxatio, its unbending.[2][5][3]

Semantic evolution

The TLL counts only three examples in Cicero and one in Scribonius Largus; from the middle of the 4th century it returns, only in prose, above all in Christian and medical writers.[3] Besides the relaxing of the mind it meant the easing of a condition such as pain,[2][5] and in its literal sense the loosening of something tight, as of the skin in Scribonius Largus' remedy for headache.[2] Later writers used it of the loosening of a bird's feathers (Augustine) and of the lessening of a quality (Boethius).[3]

In Church Latin it meant ease and relief.[6] Medieval documents used it for the remission of a payment or discharge, for a pardon, and for the release of a prisoner.[7] English borrowed it in the late 14th century for a hernia.[8] From the mid-15th century the English word also meant the remission of a burden or penalty.[8]
