To do so, the bottle is suitably canted (6)
I believe the answer is:
decant
'to do' is the definition.
The answer and definition can be both to do with motion as well as being verbs in their base form.
Maybe there's a link between them I don't understand?
'the bottle is suitably canted' is the wordplay.
'canted' anagrams to 'DECANT'.
Though, I am not sure how the anagram is indicated.
'so' is the link.
Can you help me to learn more?
(Other definitions for decant that I've seen before include "Take (wine) off lees" , "Discharge" , "Gradually pour from one container to another" , "Pour from bottle into table container, say wine" , "Pour wine from bottle to table jug" .)
