Horse showing a measure of love? (5)
I believe the answer is:
pinto
'horse' is the definition.
(pinto is a kind of horse)
'a measure of love?' is the wordplay.
I cannot quite understand how this works, but
'measure' could be 'pint' (pint is a kind of measure) and 'pint' is found in the answer.
'of' could be 'o' and 'o' is found within the answer.
No letters remain.
This explanation may well be incorrect...
'showing' acts as a link.
Can you help me to learn more?
(Other definitions for pinto that I've seen before include "patchy horse" , "Spotted or piebald horse" , "Mount" , "A piebald pony" , "H [HORSE]" .)
