Mother of twins? (4)

I believe the answer is:

mama

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

This might be a double definition.

'mother' is the first definition.
(mama informally means mother)

'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 mama that I've seen before include "Mum" , "Mummy" , "Mature woman" , "Mother" , "Dam" .)

I've seen this clue in the Evening Standard.
