A point that's sore, perhaps, will never be better (5)
I believe the answer is:
worse
'be better' is the definition.
(thesaurus)
'a point that's sore perhaps' is the wordplay.
'a point' becomes 'w' (West).
'that's' says to put letters next to each other.
'perhaps' indicates an anagram.
'sore' is an anagram of 'orse'.
'w'+'orse'='WORSE'
'will never' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for worse that I've seen before include "More severe; less well" , "Less satisfactory" , "Opposite of better" , "Inferior to another" , "Less good" .)
