Capitulates and gives the cake free (6,2,3,6)

'capitulates' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'and gives the cake free' is the wordplay.
I cannot quite see how this works, but
'and' could be 'n' (common abbreviation for 'and') and 'n' is present in the answer.
'gives' could be 'throws' ('throw' can be a synonym of 'give') and 'throws' is present in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
'cake' could be 'sponge' (sponge cake is a kind of cake) and 'sponge' is found in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
