Local fellow's youngster (4)
I believe the answer is:
calf
'youngster' is the definition.
(I've seen this before)
'local fellow's' is the wordplay.
'CALF' is hidden in amongst the letters.
However, I am unsure how this is indicated.
Can you help me to learn more?
(Other definitions for calf that I've seen before include "stocking filler" , "Young cow - part of the leg" , "Young cow or bull" , "A little lower" , "beef" .)
