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. In Italian, for example, present indicative finisco 'I finish' contains the form of the infix, while present indicative finiamo 'we finish' does not, yet the only difference in meaning is that of person subject; the infix is now semantically inert.

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.

• apiscor, apisci, aptus sum reach
• cresco, crescere, crevi, cretus come into being, spring up, grow up
• convalesco, convalescere, convalui recover, get better, grow strong
• disco, discere, didici learn
• irascor, irasci, iratus sum be in a rage
• lapidesco, lapidescere become stone
• misceo, miscere, miscui, mixtus mix
• nanciscor, nancisci, nactus/nanctus sum get
• nosco, noscere, novi, notus get to know
• obdormisco, obdormiscere, obdormivi, obdormitus fall asleep
• posco, poscere, poposci demand
• proficiscor, proficisci, profectus sum set out
• rubesco, rubescere, rubui (<rubeo) to grow red, redden

Ancient Greek

Greek also uses -sk- to show inchoative force in the present stem. -σκ- is added to verb-stems ending in vowels, -ισκ- to consonant stems.

• ἀρέσκω "I please", "appease" (first aorist ἤρεσα "I appeased")
• φάσκω "I say" (from φημί, same meaning)
• εὑρίσκω "I find" (second aorist ηὗρον "I found")

Swedish

In Swedish, inchoative verbs end in -na. Some examples and their non-inchoative counterparts:

• att blekna, to go pale; att bleka, to bleach
• att tystna, to fall silent; att tysta, to silence
• att fastna, to get stuck; att fästa, to attach
• att hårdna, to be hardened; att härda, to harden
• att kallna, to become cold; att kyla, to cool
• att ruttna, to rot; att röta, to cause something to rot

This class of verbs is today not productive, and the umlaut relationship between some inchoative verbs and their non-inchoative counterparts indicates that they in fact are quite old.
