Endless bohemian love for animal (5)
I believe the answer is:
hippo
'for animal' is the definition.
(I've seen this before)
'endless bohemian love' is the wordplay.
'endless' means to remove the last letter.
'bohemian' becomes 'hippy' (hippy is a type of bohemian or nonconformist).
'love' becomes 'o' (love means zero in tennis).
'hippy' with its last letter taken off is 'hipp'.
'hipp'+'o'='HIPPO'
(Other definitions for hippo that I've seen before include "Augustine looked after" , "Afr. river mammal" , "Aquatic pachyderm" , "Wallowing creature" , "One thick-skinned" .)
