Trudge wearily from drunken parties (7)
I believe the answer is:
traipse
'trudge wearily' is the definition.
'traipse' can be an answer for 'trudge' (I've seen this in another clue). I am not sure about the 'wearily' bit.
'drunken parties' is the wordplay.
'drunken' is an anagram indicator.
'parties' with letters rearranged gives 'TRAIPSE'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for traipse that I've seen before include "Trudge or tramp in parties" , "Pirates (anag) -- walk without 9" , "Plod - trek" , "Trudge around" , "make slow progress" .)
