Anxiety after nut married current leader in education (12)
I believe the answer is:
headmistress
'leader in education' is the definition.
(someone in charge of a school)
'anxiety after nut married current' is the wordplay.
I cannot really see how this works, but
'anxiety' could be 'stress' (I've seen this before) and 'stress' is present in the answer.
'nut' could be 'head' (I've seen this in other clues) and 'head' is found within the answer.
'married' could be 'm' and 'm' is located in the answer.
'current' could be 'i' (symbol for electric current) and 'i' is found in the answer.
No letters remain.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for headmistress that I've seen before include "Teacher" , "School principal" , "Female school leader" , "Person in charge of a school" .)
