Exercises. Tailender went to the front after I'm driven (8)
I believe the answer is:
impelled
'driven' is the definition.
(synonyms)
'exercises tailender went to the front after i'm' is the wordplay.
I cannot quite see how this works, but
'exercises' could be 'pe' (Physical Education class) and 'pe' is found in the answer.
'went' could be 'led' (leading is a kind of going) and 'led' is found in the answer.
'i'm' could be 'im' and 'im' is located in the answer.
A single letter 'l' remains which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for impelled that I've seen before include "Urged or forced to action" , "Driven to do something" , "Constrained" .)
