Supported right through when one transgressed (7)
I believe the answer is:
strayed
'transgressed' is the definition.
The definition and answer can be both to do with motion as well as being past participle verbs.
Maybe they are linked in a way I don't understand?
'supported right through when one' is the wordplay.
I cannot really see how this works, but
'right' could be 'r' (common abbreviation) and 'r' is found in the answer.
'supported' could be 'stayed' (I've seen this before) and 'stayed' is present in the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for strayed that I've seen before include "Wandered; digressed" , "Dry seat (anag) - got lost" , "Went off the track" , "Wandered (from path)" , "Went wrong" .)
