Acting talent of bachelor on electronic boat (10)
I believe the answer is:
stagecraft
'acting talent' is the definition.
The answer and definition can be both related to thinking as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'of bachelor on electronic boat' is the wordplay.
'of bachelor' becomes 'stag' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'on' means one lot of letters go next to another (in a down clue, letters appear on others).
'electronic' becomes 'e' (as in e-mail or e-books).
'boat' becomes 'craft' (boat is a type of craft).
'stag'+'e'+'craft'='STAGECRAFT'
Can you help me to learn more?
(Other definitions for stagecraft that I've seen before include "What playwright has" , "capacity for top performance?" , "Art of boarding" .)
