Origin: IE [Indo-European] [775] * h₃ekʷ- `see'

Etymology: As basis of all these formen served an in its original function unclear word ὀπ- ('see' or `eye'), which is also contained in ὄπις, ὄσσε, ὄμμα, ὤψ (s. vv.); ὄσσε from *ὄκ-ι̯ε points to IE * h₃ekʷ-, which has several representatives in many IE languages; cf. on ὄσσε.
