Paradigm of -υ ending word


If ἄγλυ, a word of Scythian origin, had a paradigm, what would it look like?
Would it look like any of the third declension neuters ending in , e.g., ἄστυ, δόρυ, πῶυ?
(the paradigm of ἄστυ is ἄστε-/ἄστη, of πῶυ is πώε-, of δόρυ is δόρατ-)
Or would it be heteroclitic?

It's impossible to say if the word isn't attested in any other form.

If I had a brother, would he like noodles? If my grandmother had balls, would she be my grandfather?
