Etymology: The first seems from *ἅ-δρυα (consisting) of one (single) tree, ἁ- < *sm̥- and δρῦς. For the meaning one single cf. μώνυχες, s.v. ὄνυξ. But in the third meaning it is a variant of μάδρυα, which is non-IE (s. there), so it is probably folk-etymology (compounds with δρυ- are rare and doubtful; see DELG s.v. δρῦς). (One might consider that the kernel of these stone-fruits, in some cases, easily falls in two parts, which resemble a canoe.) - On the second part nothing can be said. - On the third see μάδρυα.
