Makes fun of the frantic puss with the tail caught in it (5,2)
I believe the answer is:
sends up
'makes fun' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'the frantic puss with the tail caught in it' is the wordplay.
'the frantic' indicates an anagram (I've seen this in other clues).
'with' says to put letters next to each other.
'tail' indicates one should take the final letters.
'caught' becomes 'nd' (I can't explain this - if you can you should give a lot more credence to this answer).
'in it' indicates putting letters inside.
The final letter of 'the' is 'e'.
'puss' after 'e' is 'epuss'.
'epuss' with letters rearranged gives 'sesup'.
'sesup' placed around 'nd' is 'SENDS UP'.
'of' acts as a link.
Can you help me to learn more?
(Another definition for sends up that I've seen is " Takes the mickey".)
