Analysis. adinna (not given) + dāyī (taking); literally 'taking what is not given'. A-dinna is the negative participle of deti 'gives', making adinna 'not offered, not given'. Dāyī is the agent noun from √dā 'to take/give' (here in the sense 'to take'). The compound forms an agent noun: 'one who takes what is not given'.
Etymology. a- (without) + dinna (given, past participle of deti, to give) + dāyī (agent noun of √dā, to take). Deti descends from PIE *deh₃ 'to give'; cognates include English 'dare' (originally 'to give'), Latin 'dare', Sanskrit 'dāti'. The a- prefix is plain negation (English 'un-', Greek 'a-'). In the canon, adinnādāna (stealing) is the second of the five precepts; adinnādāyī denotes one who violates the second precept against taking what is not given.
