Remove twist from one drink I left (7)
I believe the answer is:
untwine
'remove' is the definition.
Although both the answer and definition are verbs in their base form, I don't understand how they can define each other.
'twist from one drink i left' is the wordplay.
I cannot quite understand how this works, but
'twist' could be 'twine' (twining is a kind of twisting) and 'twine' is found within the answer.
'one' could be 'un' (northern English dialect form of 'one') and 'un' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for untwine that I've seen before include "Take the string off" , "Release" , "Separate" , "Ravel to be dealt with" , "Disentangle" .)
