Bird strugglin' for breath? (6)
I believe the answer is:
puffin
'bird' is the definition.
(puffin is a kind of bird)
'strugglin' for breath?' is the wordplay.
'strugglin'' becomes 'in' (I can't justify this - if you can you should give a lot more credence to this answer).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'breath?' becomes 'puff' (puff is a kind of breath).
'in' after 'puff' is 'PUFFIN'.
Can you help me to learn more?
(Other definitions for puffin that I've seen before include "Bird with colourful beak" , "Bright-billed bird" , "Northern seabird with short neck and brightly coloured bill" , "Seabird with brightly coloured bill - sounds out of breath" , "Large-beaked sea bird" .)
