Potentially big game that woman starts with deep breath (7)
I believe the answer is:
panther
'potentially big game that woman starts with deep breath' is the definition.
I can't judge whether this defines the answer.
'potentially big game that woman' is the wordplay.
'potentially big game' becomes 'pant' (I can't justify this - if you can you should give a lot more credence to this answer).
'that woman' becomes 'her' ('her' refers to a woman).
'pant'+'her'='PANTHER'
Can you help me to learn more?
(Other definitions for panther that I've seen before include "kind of feline" , "Black leopard" , "Bagheera?" , "See 2" , "big pussycat" .)
