Discover path, then stray from it delivering fruit (6)
I believe the answer is:
raisin
'fruit' is the definition.
(raisin is a kind of fruit)
'discover path then stray' is the wordplay.
'discover' means to look at the middle letters (I've seen 'discovered' mean this).
'path' becomes 'trail' (trail is a kind of path).
'then stray' becomes 'sin' (I can't explain this - if you can you should believe this answer much more).
The middle of 'trail' is 'rai'.
'rai'+'sin'='RAISIN'
'from it delivering' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for raisin that I've seen before include "Dried grape used in cakes" , "Cultivating" , "Dried 18" , "fruit product" , "sultana, say" .)
