Heir, male child, Channel Islands resident (5)
I believe the answer is:
scion
'heir' is the definition.
(I've seen this before)
'male child channel islands resident' is the wordplay.
I cannot quite understand how this works, but
'islands' could be 'ci' (Channel Islands) and 'ci' is found within the answer.
'male' could be 'son' (male child) and 'son' is found in the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for scion that I've seen before include "Young family member" , "Issue" , "Descendant - heir" , "Young shoot or twig" , "Young shoot/twig" .)
