adjective (nominative singular masculine)
Analysis. su- (well, good, easy) + vaco (speech, words from √vac "speak"). Lit. "of good speech" or "having easy words"—one who speaks well or to whom speaking is easy.
Etymology. su- from Indo-European *su- (good, well, same root as Greek εὖ eu- in eulogy); vac from the root *wek- "speak" (cognate with Latin vocem, English voice). The compound conveys both "easy to address" and "amenable to words."
