Asks to name the child (5,2)
I believe the answer is:
calls on
'asks' is the definition.
The definition and answer can be both to do with communicating as well as being verbs in their -s form.
Maybe they are linked in a way I don't understand?
'name the child' is the wordplay.
'name' becomes 'call' (to call them someone something is to name them).
'the child' becomes 'son' (male child).
'call'+'son'='CALLS ON'
'to' is the link.
Can you help me to learn more?
(Another definition for calls on that I've seen is " Visits".)
