He was inundated with entries from couples (4)

I believe the answer is:

noah

I'm a little stuck... Click here to teach me more about this clue!

'he' is the definition.

'inundated with entries from couples' is the wordplay.
I cannot really understand how this works, but
'from' could be 'o' (I've seen this in other clues) and 'o' is found within the answer.
The remaining letters 'nah' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

'was' is the link.

Can you help me to learn more?

(Other definitions for noah that I've seen before include "Old ship builder" , "Webster?" , "First collector of animals?" , "Biblical sailor" , "Biblical arkwright" .)
