3rd person singular present indicative of kammati
Analysis. kamma (action, deed) + inti (3rd person singular present ending). The form treats kamma as a verb stem, though kamma itself is primarily a noun; here it is verbalised as 'to act' or 'to do'.
Etymology. From √kamm-, cognate with Sanskrit karman (action, deed, work) and English 'grammar' (from Greek grammata, the written record of action). The root's concrete sense is 'to make, to do, to effect'; it lies beneath most Indo-European languages' words for craft and art (Greek cheirurgos, Latin manus). In Pali doctrine, kamma is the volitional deed that bears fruit (phala) in this life and future rebirths—the engine of saṁsāra.
