Suggest tip for racehorse (5-2-7)
I believe the answer is:
point to pointer
'racehorse' is the definition.
(I've seen this before)
'suggest tip for' is the wordplay.
I cannot quite see how this works, but
'suggest' could be 'point' (I've seen this before) and 'point' is found in the answer.
'tip' could be 'pointer' (I've seen this before) and 'pointer' is present in the answer.
'for' could be 'to' (eg both can mean 'in the opinion of') and 'to' is found in the answer.
No letters remain.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for point to pointer that I've seen before include "does God do so in The Creation of Adam?" , "Producing horse" , "cross-country racer" , "Racehorse" .)
