Forms

exténuer[1]

Etymology

It is borrowed from Latin extenuō (“to make thin, to weaken, to lessen”), from ex- and tenuis (“thin, fine”).[2][3][4][5][6] The GLLF takes the verb from tenuō (“to make thin”), itself from the adjective.[7] Compare Old Occitan extenuar, Spanish extenuar and Italian estenuare.[8]

Earliest recorded meaning

The TLFi's first record is the past participle in a 1478 text of Guy de Chauliac's Grande Chirurgie: le corps devient extenué “the body becomes wasted”.[2][3] The Petit Robert and the Grand Robert date the word to 1344, or the 14th century.[9][4]

Semantic evolution

The active verb is found from 1495 in the sense “to wear out, to sap the strength of”.[2][3] In the 16th century it also took up senses of its Latin source: figuratively “to lessen greatly, to play down” (1541, Calvin) and literally “to make very thin” (1552, Robert Estienne); these are now almost out of use.[3][7] Rabelais (1534) speaks of drying, extenuantes foods.[2] In the intellectual sense of making less, atténuer has taken its place.[5]

Today it is used mostly in the passive, in the past participle exténué and in the reflexive s'exténuer (1734).[3] The adjective exténuant “exhausting” dates from 1845.[3]
