Rod possibly set out to cover two opposing points (7)
I believe the answer is:
stewart
'rod' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
'set out to cover two opposing points' is the wordplay.
'set out' becomes 'start' (synonyms).
'to cover' indicates putting letters inside.
'two opposing points' becomes 'ew' (I can't explain this - if you can you should give a lot more credence to this answer).
'start' going around 'ew' is 'STEWART'.
'possibly' acts as a link.
Can you help me to learn more?
(Other definitions for stewart that I've seen before include "chap..." , "Man" , "Racing driver" , "Scottish house" , "Northern clan" .)
