Young animal gets fish after some time (8)
I believe the answer is:
yearling
'young animal' is the definition.
'yearling' can be an answer for 'animal' (yearling is a kind of animal). I'm not certain of the 'young' bit.
'gets fish after some time' is the wordplay.
'gets fish' becomes 'ling' (I can't explain this - if you can you should give a lot more credence to this answer).
'after' is a charade indicator (letters next to each other).
'some time' becomes 'year' (year is a unit of time).
'ling' after 'year' is 'YEARLING'.
Can you help me to learn more?
(Other definitions for yearling that I've seen before include "Relaying (anag.)" , "Youngster" , "Twelve-month old animal" , "Animal in its second 12 months" , "A racehorse under 2" .)
