A chap welcoming return of enemy politicians when Congress officially gets going (3,2,7)
I believe the answer is:
age of consent
'going' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see an association between them that I can't see?
'a chap welcoming return of enemy politicians when congress officially' is the wordplay.
I cannot really understand how this works, but
'a' is within the answer.
'chap' could be 'con' and 'con' is found in the answer.
'of' could be 'o' and 'o' is present in the answer.
'when' could be 'e' (I've seen this in other clues) and 'e' is present in the answer.
This may be the basis of clue (or it may be nonsense).
'gets' is the link.
Can you help me to learn more?
(Other definitions for age of consent that I've seen before include "Time when agreement becomes legally valid" , "Legal majority?" , "Beyond which relations allowed" .)
