Fish found by youth leader is fishy (5)
I believe the answer is:
shady
'fishy' is the definition.
(I know that fishy can be written as shady)
'fish found by youth leader' is the wordplay.
I cannot quite understand how this works, but
'fish' could be 'shad' (shad is a kind of fish) and 'shad' is found within the answer.
'youth' could be 'y' and 'y' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'is' is the link.
Can you help me to learn more?
(Other definitions for shady that I've seen before include "Questionably legal" , "underhand" , "Dishonest" , "Fishy; unlit" , "Suspicious, fishy" .)
