ἰαίνω

Ancient Greek

Etymology

Probably from Proto-Indo-European *h₁eysh₂-n-ye-ti, a nasal ye-present of *h₁eysh₂- (“to strengthen, propel”), whence also Sanskrit इषण्यति (iṣaṇyati, “to urge on, incite”) (though the semantics are not particularly strong, nor particularly weak). See also ῑ̓άομαι (īáomai, “to cure, repair”), as well as the primary Sanskrit formations इष्यति (iṣyati, “to impel, send”), इष्णाति (iṣṇāti, “to incite, throw, swing”).^[1]
