Right in position for good healthy fun (5)
I believe the answer is:
sport
'good healthy fun' is the definition.
'sport' can be an answer for 'fun' (synonyms). I am unsure of the 'good healthy' bit.
'right in position' is the wordplay.
'right' becomes 'r' (common abbreviation).
'in' indicates putting letters inside.
'position' becomes 'spot' (synonyms).
'r' going inside 'spot' is 'SPORT'.
'for' is the link.
Can you help me to learn more?
(Other definitions for sport that I've seen before include "Wear - game - generous type" , "Eg, rugby" , "Recreation, play" , "Games" , "eg Tennis" .)
