Drunk, Odile would be well so (5)
I believe the answer is:
oiled
'drunk' is the definition.
(I've seen this before)
'odile would be well so' is the wordplay.
'odile' anagrams to 'OILED'.
Though, I'm not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for oiled that I've seen before include "Lubricated (with drink?)" , "tipsy" , "running smoothly?" , "wasted" , "Greased; drunk" .)
