Oblique poetry on coaches one's forgotten (10)
I believe the answer is:
transverse
'oblique' is the definition.
(thesaurus)
'poetry on coaches one's forgotten' is the wordplay.
I cannot quite understand how this works, but
'poetry' could be 'verse' ('verse' can be a synonym of 'poetry') and 'verse' is found in the answer.
'one's' could be 'ans' (I've seen this in other clues) and 'ans' is located in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for transverse that I've seen before include "Extending across something" , "Crossing" , "Extending across (the long axis)" , "go in 6 ac [CRISSCROSS]" , "Cross" .)
