State schoolteacher (4)
I believe the answer is:
miss
This might be a double definition.
'state' is the first definition.
(I've seen this before)
'schoolteacher' is the second definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for miss that I've seen before include "One is as good as a mile" , "Fail to hit; girl" , "Feel the loss of - schoolgirl" , "maiden" , "Fail to meet - girl" .)
