Is troublesome cat about to drink? (4,2)
I believe the answer is:
acts up
'is' is the definition.
The answer and definition can be both to do with social activities as well as being verbs in their -s form.
Perhaps you can see an association between them that I can't see?
'troublesome cat about to drink?' is the wordplay.
I cannot really understand how this works, but
an anagram of 'cat' is 'act' which is located in the answer.
'drink?' could be 'sup' (to sup is to drink) and 'sup' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for acts up that I've seen before include "Malfunctions" , "Behaves in a troublesome way" , "Fails to function properly or behaves badly" , "Misbehaves badly" , "Behaves badly (colloq.)" .)
