From Proto-Italic *nokeō, from Proto-Indo-European *noḱéye-, causative of the root *neḱ- (“perish, disappear”). Cognate with Sanskrit नश्यति (naśyati, “disappear, perish”).
noceō (present infinitive nocēre, perfect active nocuī, supine nocitum); second conjugation
- (with dative) I injure, do harm to, hurt, damage
- The injury caused may be physical or emotional.
- In practice, the only passive forms met with in Latin are the third-person singular forms.
1The present passive infinitive in -ier is a rare poetic form which is attested for this verb.
