Thus Tom gets in tizzy, after answer given in court (7)
I believe the answer is:
catflap
'thus tom gets' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'tizzy after answer given in court' is the wordplay.
'tizzy' becomes 'flap' (I've seen this before).
'after' is a charade indicator (letters next to each other).
'answer' becomes 'a' (abbreviation eg in Q and A).
'given in' indicates putting letters inside.
'court' becomes 'ct' (abbreviation used in road names).
'a' going within 'ct' is 'cat'.
'flap' after 'cat' is 'CATFLAP'.
'in' is the link.
Can you help me to learn more?
(Another definition for catflap that I've seen is " small entrance".)
