Irresistibly derives from English irresistible, formed in English from the prefix in- (from Latin in-, from Proto-Indo-European ne-, meaning "not") combined with resistible, which comes from Latin resistibilis based on the verb resistere (re- plus sistere, from Proto-Indo-European oyd-, meaning "to stand").
