feminine nominative singular (parikammavācanā form with -api enclitic)
Analysis. chakaṇakā (hot cow dung) + api (even, also); the -api particle attaches to the accusative chakaṇakāyaṃ or ablative chakaṇakāyā in the original clause, sandhi-contracted here to chakaṇakāyapi.
Etymology. chakaṇakā is a feminine diminutive or descriptive term for heated cow dung, used in Brahminical and domestic purification rites. The root is uncertain; it may derive from a word for 'heat' or 'burning', but no secure Indo-European cognate is available. The -api particle is the enclitic 'even, also' (related to Sanskrit api, Old English ape 'ape' in the sense of 'imitate closely'; more likely cognate with Greek epi 'upon, at'), which adds emphasis or inclusivity to whatever precedes it.
