Mix thoroughly in jug (4)
I believe the answer is:
stir
This clue could be a double definition.
'mix thoroughly' is the first definition.
'stir' can be an answer for 'mix' (I've seen this before). I'm unsure of the 'thoroughly' bit.
'jug' is the second definition.
(I've seen this before)
'in' is the link.
Can you help me to learn more?
(Other definitions for stir that I've seen before include "Wake up - prison" , "jail" , "Whisk, agitate" , "Stimulate; prison" , "Move around in a liquid" .)
