Worried after student disregarded restriction to copy (7)
I believe the answer is:
imitate
'copy' is the definition.
(synonyms)
'worried after student disregarded restriction' is the wordplay.
I cannot quite see how this works, but
'worried' could be 'ate' (something worrying may eat someone up) and 'ate' is found in the answer.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for imitate that I've seen before include "Mimic or follow as a model" , "Fake" , "Take as a model" , "Follow suit" , "Parrot" .)
