Forms

ᾰ̔́πτω (háptō) [1]

Etymology

It is inherited from Proto-Hellenic *áptō, whose further origin is debated.[1] Beekes, following van Beek and an older proposal by Kretschmer, derives it from Proto-Indo-European *h₂ep- (“to join, fit”), the root of Hittite ḫapp- (“to join”) and Latin aptus (“fit, apt”).[2][3] On this view the rough breathing is secondary, after verbs such as ἕπω (hépō) from Proto-Indo-European *sep-, and the aspirate of ἁφή (haphḗ, “grip”) and the other derivatives is analogical.[2] Furnée took ἀφάω (apháō) as evidence of a Pre-Greek origin, but Beekes explains that verb as a denominative of the noun for “grip”.[2] Others have compared ἰάπτω (iáptō, “to send forth”) and Old Armenian ափ (apʻ, “palm of the hand”).[1] The present stem adds a ⟨τ⟩ to the root.[1]

Earliest recorded meaning

In Homer the middle means to take hold of something, with the genitive, and the active, to fasten, occurs once, of a string fixed at both ends on a lyre in the Odyssey.[4][5] The Iliad also says of spears that they “reach” their mark.[4]

Semantic evolution

From fastening and grasping, the middle developed many figurative senses in Classical Greek: to engage in or undertake a task (Sophocles, Thucydides), to attack (Pindar, Aeschylus), to lay hands on property and to touch the mind (Plato), to perceive and apprehend (Sophocles, Aristotle), to attain the truth (Plato), and to have intercourse with a woman.[4] In geometry it was used of bodies and lines that meet or touch (Aristotle, Euclid).[4] The active came to mean to kindle, by bringing fire into contact, from Herodotus and Aeschylus on.[4]

In the New Testament the active is to light a lamp or a fire, and the middle to touch or take hold of, also of sexual relations (1 Corinthians 7:1).[6][4] Medieval vernacular Greek kept Byzantine Greek άπτω (áptō), and the form survives in dialects.[7] The standard language has the learned middle Modern Greek άπτομαι (áptome), to relate to or concern a subject.[8][3] English haptic (1890) comes from the derived adjective ἁπτικός (haptikós).[9]
