sandhi form: amhākaṃ + api
Analysis. amhākaṃ (accusative plural of ahaṃ, "us") + api ("even, also") = "even for us". The form contracts across a word boundary, with the final ṃ of amhākaṃ assimilating before the initial vowel of api.
Etymology. ahaṃ is the first-person singular pronoun, cognate with Sanskrit aham and English "I" (from Proto-Indo-European *éǵh₂om). The plural amhākaṃ ("we, us, our") extends this root. api ("even, also, too") is an enclitic particle of uncertain origin, perhaps originally meaning "on top of" or "additionally".
