Conclusion from some friend in gym (6)
I believe the answer is:
ending
'conclusion' is the definition.
(I know that conclusion can be written as ending)
'some friend in gym' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'ENDING' can be found hidden inside 'friend in gym'.
'from' acts as a link.
(Other definitions for ending that I've seen before include "Finishing" , "Gin den (anag.)" , "Closing down" , "terminal" , "Final part" .)
