apiō (present infinitive apere, supine aptum); third (-iō variant) conjugation, no perfect stem[1]
Etymology
It is probably inherited from Proto-Italic *apjō.[1] Two roots have been proposed: Proto-Indo-European *h₁ep- (“to grab, get”), the root of apīscor, for which the LIV suggests ⟨*h₁p-yé-ti⟩ and de Vaan an athematic i-present ⟨*h₁p-i-⟩; or Proto-Indo-European *h₂ep- (“to attach”), with Hittite ḫapp- (“to join”) and Ancient Greek ἅπτω (háptō, “to fasten”).[1] De Vaan sees no need to separate ⟨apiō⟩ from ⟨apīscor⟩, which keeps the general sense, while ⟨apiō⟩ was specialised for tying.[2] The OLD compares Sanskrit आप्त (āptá, “suitable”) and apud.[3]
Earliest recorded meaning
Gaffiot's sources are Festus, Servius on Virgil and Isidore.[4] The only form in common use is the participle aptus.[1]
Semantic evolution
It meant to fasten, attach, bind, and is found chiefly in the participle aptus “fastened, fitted”.[3][1]
