Etymology

It is from Latin adiectīvus (“added”), used as a noun in the neuter.[2][1] Wiktionary explains it as an ellipsis of a phrase with nōmen (“noun”), “additional noun”, which calques Ancient Greek ὄνομα ἐπίθετον (ónoma epítheton).[1]

Earliest recorded meaning

It is found in the grammar of Donatus,[3][4] for the adjective as opposed to the substantive, positivum.[3]

Semantic evolution

It is common in the Latin grammarians:[3] Priscian defines the adjective as what is added to proper or common nouns,[3] and Isidore of Seville says that what the Greeks call epithets are called adiectiva or superposita in Latin.[3]

English adjective comes from it, through Old French.[5]
