3rd person plural optative
Analysis. upa + pajjati: upa (near, alongside) + pajjati (happens, befits), literally 'comes about nearby' or 'draws near', hence in rebirth context 'comes to be reborn in a state', and in ethical context 'is fitting, acceptable'.
Etymology. √pad (fall, go) underlies pajjati; upa- shows approach and proximity. In rebirth doctrine (saṃsāra), upapajjati describes a being's reappearance in a new existence—the literal sense of 'going toward' (a destination) becomes the metaphor for transmigration. English cognates: pad (as in 'pathway'), pad itself < PIE *peh₂- (to tread); upa- relates to English 'up' and Greek hypo- (under, up close).
