Weakens enough to point to the wrong list (5)
I believe the answer is:
wilts
'weakens enough' is the definition.
'wilts' can be an answer for 'weakens' (wilting is a kind of weakening). I am unsure of the 'enough' bit.
'point to the wrong list' is the wordplay.
'point' becomes 'w' (W is an example**).
'to the wrong' indicates an anagram.
'list' anagrammed gives 'ilts'.
'w'+'ilts'='WILTS'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for wilts that I've seen before include "Droops; county (abbr.)" , "A county (abbr.); suffers from 1" , "Count[r?]y" , "Flags" , "(Of foliage) goes limp" .)
