Female supporters are heard to feed Manx crocodiles (4)
I believe the answer is:
bras
'female supporters' is the definition.
'bras' can be an answer for 'supporters' (a bra gives support to breasts). I am unsure of the 'female' bit.
'are heard to feed manx crocodiles' is the wordplay.
'are heard' becomes 'r' (I've seen this in other clues).
'to feed' is an insertion indicator (one word is fed into another).
'manx crocodiles' becomes 'bas' (I can't explain this - if you can you should believe this answer much more).
'r' inserted into 'bas' is 'BRAS'.
Can you help me to learn more?
(Other definitions for bras that I've seen before include "supports" , "Female undergarments" , "Items in womenswear" , "Garments with cups" , "They support" .)
