- n. Plural form of hapax.
Sorry, no etymologies found.
Since the forms are abbreviated here and since these epithets appear to be hapaxes, one can only surmise the full forms.
The oldest Greek has many hapaxes, names for forgotten farming instruments and sexual instruments that early scholars thought were more suitably translated as sea creatures.
This analysis is more optimal since if we think of this as a game of cards, two attested words and a dis legomenon i.e. a word attested only twice beats two hapaxes any day.
