gerund
Analysis. ā + √gam, 'coming toward the speaker'; used as a gerund meaning 'having come to', hence 'on the basis of', 'owing to', 'concerning'. The prefix ā reverses the motion of √gam from 'going away' to 'coming toward'.
Etymology. ā (toward the speaker) + √gam (go, come). √gam is the same root as Latin venīre (come) and English come (via Old English cuman); it is cognate with Sanskrit gam- and appears in Pali as gacchati 'goes'. The prefix ā (Sanskrit ā) reverses the direction of motion, turning 'go' into 'come (to)', and the gerund form āgamma preserves the concrete sense of motion while acquiring the abstract sense of 'basis' or 'reason'.
