Forms
lasser[1]
Etymology
It is inherited from Latin lassō (“to tire, weary”),[2][3][4] from lassus (“tired”), the source of las.[5][6][4] De Vaan reconstructs the adjective as Proto-Indo-European *lh₁d-to- (“tired”), with a d-enlargement of the root *leh₁- (“to let”).[7] Cognate with Occitan lassar, Catalan llassar and Italian lassare.[8]
Earliest recorded meaning
The Grand Robert, the GLLF and Rey date it to the Chanson de Roland (about 1100), used intransitively for “to grow tired”: Lasserat Charles.[5][6][4][8] The TLFi's first record is later, in the Roman d'Eneas (about 1165), as a transitive verb “to tire physically” and as reflexive se lasser “to grow weary”.[2]
Semantic evolution
Old French used the verb and its derivatives of bodily tiredness.[4] From the 13th century (Jean de Meun, about 1265) it came to mean “to tire by boring”, and in 1485 “to wear down, discourage”; this moral sense now prevails, and the physical one is old-fashioned.[4][6][9][2] The construction se lasser de drove out classical se lasser à.[4] The same shift is seen in the adjectives lassé (about 1160) and lassant (1680).[4] The derivative délasser, rare before the 16th century, has gone its own way and means “to relax”.[3][4]
