Forms
īnfīnītīvus (feminine īnfīnītīva, neuter īnfīnītīvum); first/second-declension adjective[1]
Etymology
It is formed from Latin īnfīnītus (“unlimited, indefinite”) + -īvus,[1][2] and the noun is used elliptically for the infinitive mood, with modus (“mood”) understood.[1] Wiktionary takes it as a loose rendering of Ancient Greek ἀπαρέμφατος (aparémphatos), “not indicated”.[1]
Earliest recorded meaning
A term of the Latin grammarians, it is found with certainty from Charisius on, according to the TLL;[2] Köbler dates Charisius to about AD 362.[3] It names the verb form that is not limited by person or number.[4][5]
Semantic evolution
Diomedes, Martianus Capella, Priscian and Isidore of Seville use it for the infinitive, as an adjective with modus or as a noun on its own.[4][6][7] The TLL notes that manuscripts often confuse it with īnfīnītus.[2] Medieval grammarians kept the term;[8][9] it was also used in the wider sense of unlimited or innumerable.[10][8]
English took it over as an adjective in the mid-15th century and as the noun infinitive in the 1510s.[5]
