Child prodigy with family gathering below, heading for Dresden (10)
I believe the answer is:
wunderkind
'child prodigy' is the definition.
(I've seen this before)
'with family gathering below heading for dresden' is the wordplay.
I cannot really understand how this works, but
'with' could be 'w' (abbreviation) and 'w' is located in the answer.
'family' could be 'kin' ('kin' can be a synonym of 'family') and 'kin' is present in the answer.
'below' could be 'under' ('under' can be a synonym of 'below') and 'under' is found within the answer.
A single letter 'd' remains which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for wunderkind that I've seen before include "Perhaps Mozart" , "One having early success" , "Extraordinary issue" , "Clever young person" , "Child prodigy" .)
