Going off to the west, walking in an ungainly way (8)
I believe the answer is:
waddling
'walking in an ungainly way' is the definition.
'waddling' can be an answer for 'walking' (thesaurus). I am not certain of the 'in an ungainly way' bit.
'going off to the west' is the wordplay.
'going off' becomes 'addling' (I am not sure about this - if you are sure you should believe this answer much more).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'the west' becomes 'W' (synonyms).
'addling' after 'w' is 'WADDLING'.
Can you help me to learn more?
(Other definitions for waddling that I've seen before include "Perhaps movement of duck" , "Dawdling (anag.)" .)
