Analysis. Sandhi form: vā (or) + api (even, also) → vāpi "or even"; also an independent noun vāpī "reservoir, dam".
Etymology. The noun vāpī is of uncertain origin, possibly non-Aryan; it appears in Sanskrit as vāpī with the same meaning (reservoir, pond). The sandhi form vāpi combines vā (disjunctive particle, from PIE *au̯e- "away, separate") + api (also, even; related to Sanskrit api, cognate with Greek apo- "away from", Latin ab "from").
