Etymology
1. From earlier *opejō, further etymology disputed.
2. * Possibly from Proto-Indo-European *h₁ep- (“to reach, seize”), whence also apīscor (“to reach, seize”), and Sanskrit आप् (āp, “to reach”), Hittite [script needed] (epp-ᶻⁱ / app-, “to reach”); and Hittite [script needed] (pai-ⁱ / pi-, “to give”), Lycian [script needed] (pije-, “to give”), and possibly Albanian jap (“to give”).
3. * Traditionally connected to Latin opīnor (“to believe”), though this is semantically difficult to explain.
4. * Semantic differences oppose also any connection to *h₃ep- (“to work”), whence Latin opus. See: Sanskrit '
आप्', Albanian '
jap'.
