arrepentir

Mane

to regret, repent

Wekî (IPA) tê gotin

/arepenˈtiɾ/

Etîmolojî

From Old Galician-Portuguese repentir (13th century, Cantigas de Santa Maria), from Vulgar Latin *repaenitīre, from Late Latin paenitīre, from Classical Latin paenitēre.
The expected outcome would have had voiced /d/; cf. the alternative form above (< Medieval Latin repoenitēre). As occurred in Old Spanish, the medieval repentir may be due to French influence.
Compare Portuguese arrepender, Spanish arrepentirse.
