Disconnect by someone taking turns (7)
I believe the answer is:
unscrew
'disconnect' is the definition.
The definition and answer can be both to do with contact as well as being verbs in their base form.
Perhaps you can see a link between them that I can't see?
'someone taking turns' is the wordplay.
I cannot quite understand how this works, but
'someone' could be 'screw' (screw is a kind of someone) and 'screw' is present in the answer.
The remaining letters 'un' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
'by' acts as a link.
Can you help me to learn more?
(Other definitions for unscrew that I've seen before include "Take off (eg, a lid)" , "Take the top off" , "Twist off (a lid or cap)" , "slack off" , "Loosen" .)
