Horse in stable -- I love name (8)
I believe the answer is:
stallion
'horse' is the definition.
(I know that stallion is a type of male horse)
'stable i love name' is the wordplay.
'stable' becomes 'stall' (I've seen this in other clues).
'love' becomes 'o' (love means zero in tennis).
'name' becomes 'n' (common abbreviation e.g. on forms).
'stall'+'i'+'o'+'n'='STALLION'
'in' acts as a link.
(Other definitions for stallion that I've seen before include "Male horse, often used for breeding" , "Mount" , "Male horse kept for breeding" , "Uncastrated adult male horse" , "Mare's mate" .)
