-isso

== Latin == === Etymology === Borrowed from Ancient Greek -ίζω (-ízō), possibly via a variant -ίσσω that existed in the dialect of Tarentum in Southern Italy (as in σαλπίσσω, λακτίσσω). The same Greek suffix was later borrowed as -izō. === Suffix === -issō (present infinitive -issāre, perfect active -issāvī, supine -issātum); first conjugation Used to form similative verbs from nouns and adjectives. ==== Usage notes ==== This form of the suffix occurs mainly in the comedies of Plautus, written at a time before the use of the letter Z in Latin words loaned from Greek was firmly established. In later time periods, the usual spelling became -izō (a variant -idiō also developed). ==== Conjugation ==== 1The present passive infinitive in -ier is a rare poetic form which is attested. === References ===
