sandhi contraction of dve + imā
Analysis. dve (two) + imā (these, nom. pl. masc./neut.); the initial vowel of imā assimilates to the final vowel of dve in rapid speech, yielding dvemā as a single phonetic unit.
Etymology. dve < dvi- (two), from Proto-Indo-European *dwoi̯-, cognates English two, German zwei, Latin duo, Sanskrit dvi-. imā is the nominative plural of idam (this, that). The contraction reflects natural sandhi vowel coalescence common in Pali speech.
