masculine nominative plural with ca enclitic
Analysis. vacchaka (young calf) + ca (and); nominative plural vacchakaṃ becomes vacchaka before ca by loss of final nasal.
Etymology. vaccha (calf) is cognate with Sanskrit vatsa and Latin vitulus (calf, weanling); the -ka suffix is a Pali diminutive forming small or young things. The root vats- may be related to vatsati (grows old, ripens), suggesting the 'ripened' or 'grown' offspring; compare Sanskrit vayaḥ (age) and English 'wax' (grow).
