gerund + emphatic particle (sandhi form vivicceva)
Analysis. vivicca (gerund, "separating") + eva (emphatic particle, "indeed, quite") — the gerund emphasizes the action itself, and eva strengthens it to "entirely" or "utterly"; often used in locative constructions (vivicceva kāmehi "secluding oneself from sense-pleasures").
Etymology. vi- (apart, asunder) + √vij/vic (to separate, move apart) — the root appears in vicaya (investigation, discrimination); cognate with Latin vice (change, in the sense of alternating/parting ways) and Greek oikos (dwelling, from the sense of "dividing into household spaces"). The prefix vi- gives the sense of thorough separation or clarity.
