Wanted the teacher indeed! (7)
I believe the answer is:
desired
'wanted' is the definition.
('desire' can be a synonym of 'want')
'teacher indeed' is the wordplay.
I cannot really see how this works, but
'teacher' could be 'sir' (way of addressing a male teacher) and 'sir' is found within the answer.
The remaining letters 'deed' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'the' is the link.
Can you help me to learn more?
(Other definitions for desired that I've seen before include "Had aspired to" , "requested" , "Sought after" , "Lusted-after" , "Wanted strongly" .)
