Position of golfer’s ball that’s deceptive (3)
I believe the answer is:
lie
'position of golfer's ball' is the definition.
(position at which a golf ball stops)
'that's deceptive' is the wordplay.
I cannot really understand how this works, but
'that's' could be 'ie' (abbreviation for 'id est', 'that is' in Latin) and 'ie' is located in the answer.
A single letter 'l' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for lie that I've seen before include "Prevaricate or recline" , "Be prone - misrepresent the facts" , "Disinformation" , "Untruth; rest" , "buried" .)
