Provide with drink - trick is to avoid getting round in (6)
I believe the answer is:
supply
'trick is to avoid getting round in' is the definition.
I can't judge whether this definition defines the answer.
'provide with drink' is the wordplay.
'provide' becomes 'ply' (synonyms).
'with' says to put letters next to each other.
'drink' becomes 'sup' (to sup is to drink).
'ply' put after 'sup' is 'SUPPLY'.
Can you help me to learn more?
(Other definitions for supply that I've seen before include "Contribute" , "Teacher, sort of" , "Give" , "Stock" , "in a compliant manner" .)
