Worked in a school that sounds rigid (6)
I believe the answer is:
taught
'worked in a school' is the definition.
I can't tell whether this defines the answer.
'sounds rigid' is the wordplay.
'sounds' shows a homophone (sound like).
'rigid' becomes 'taut' (I've seen this in another clue).
'taut' is a homophone of 'TAUGHT'.
'that' acts as a link.
Can you help me to learn more?
(Other definitions for taught that I've seen before include "disciplined" , "Tutored" , "Was coach" , "given a lesson" , "as a pupil" .)
