Forms
sinestro (feminine sinestra, masculine plural sinestri, feminine plural sinestre)[1]
Etymology
It is inherited from Late Latin sinextrum, sinister (“left”), with the vowel of dexter (“right”).[1][2][3] The same form gave Old French senestre and Spanish siniestro, and the dialects have Bolognese snéster and Friulian signéstri.[2][3][4] sinistro is the learned doublet, taken again from Latin.[5][1]
Migliorini counted this pair of doublets among the words in which the 14th century replaced the Tuscan sound shape by the Latin one, until the Latin form won.[5]
Nocentini derives Latin sinister from the base of senex (“old”) with a contrastive suffix, as the weaker, “old” hand set against dexter.[4] DEI connects it with sine (“without”), as “the one that differs from the right”.[3]
Earliest recorded meaning
DELI's first record of sinestro is in Guittone d'Arezzo, before 1294, in the sense “unfavourable, adverse”.[5] DEI puts the form in the 13th century.[3]
Semantic evolution
Petrarch uses sinestra for the left hand, and Pulci writes of Rinaldo kneeling sul lato sinestro, on his left side.[2] DEI gives Petrarch's senèstro as a 14th-century variant.[3] The noun senestro “misfortune” is in Francesco da Barberino in 1314.[5] The form is now obsolete in the standard language, but it lives on in some northern dialects.[2][1][6]
Timeline
- Before 1294 – Guittone d'Arezzo uses sinestro “adverse”.[5]
