Father of twins? (4)

I believe the answer is:

papa

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

This clue could be a double definition.

'father' is the first definition.
(papa can mean one's father)

'of twins?' is the second definition.
The definition suggests a singular noun which matches the answer.

Can you help me to learn more?

(Other definitions for papa that I've seen before include "Father; P (radio comms.)" , "The old man" , "Pop" , "Father; letter P" , "Daddy]" .)

I've seen this clue in the Evening Standard and The Globe and Mail.
