The maestro may take one in hand (5)
I believe the answer is:
baton
'hand' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'the maestro may take one' is the wordplay.
I cannot really understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
'one' could be 'a' (a thing is one thing) and 'a' is found within the answer.
The remaining letters 'bon' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for baton that I've seen before include "Short stick" , "weapon" , "Conductor's wand" , "Prohibition" , "Relay runner's stick" .)
