This etymology, which the Gudianum erroneously attributes to Apollodorus of Athens, results from a misunderstanding of sources where ἄγνυμι "to break" is given as the etymon of ἀκτή "rocky coastline", as in the Geneva scholion to Il. 11.631: ἀλφίτου ἱεροῦ ἀκτὴν] ἤτοι ἄλφιτα περιφραστικῶς, ἢ ἄρτον—ὁτὲ δὲ <τὸν> αἰγιαλὸν, ἀπὸ τοῦ ἄγνυσθαι αὐτῷ τὰ <κύματα> "alphitou hierou aktè "the flour of the sacred grain", that is, grain, with a periphrasis, or bread—but when it refers to the seashore (aigialos), <it comes> from the fact that the waves break (agnusthai) on it." Here the problem is to distinguish between ἀκτή2 "flour" and ἀκτή1 "rocky coast", and the ἄγνυσθαι τὰ <κύματα> is provided as the etymon of ἀκτή1, not of αἰγιαλός which is mentioned only as a gloss of ἀκτή1 to make the meaning of the word clear. This etymology of ἀκτή1 was standard and is repeated in many sources (see ἀκτή1 / ἄγνυμι). The problem is that some compilers took the ἄγνυσθαι, etymon of ἀκτή, as the etymon of the gloss αἰγιαλός. It is likely that Apollodorus had ἄγνυμι as the etymon of ἀκτή, not of αἰγιαλός, but the compilers did not understand properly (accordingly, De Stefani's remark that the fragment is not in the edition of Apollodorus' fragments is pointless since this is probably not Apollodorus' etymology)
