Inchoative verb

An inchoative verb, sometimes called an "inceptive" verb, shows a process of beginning or becoming. Productive inchoative infixes exist in several languages, including Latin and Ancient Greek, and consequently some Romance languages. Not all verbs with inchoative infixes have retained their inceptive meaning.

Latin

The Latin language uses the infix -sc- to show inchoative force. The infix is normally seen in the present tense stem, and is not present in the third and fourth principal parts.
