Where to pull up what may be pulled out (5)
I believe the answer is:
stops
'where to pull up what may be pulled out' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'where to pull up' is the wordplay.
'where' becomes 's' (I am not sure about this - if you are sure you should believe this answer much more).
'to' means one lot of letters go next to another (I've seen this in other clues).
'pull up' becomes 'stop' (I've seen this in another clue).
's' put after 'stop' is 'STOPS'.
Can you help me to learn more?
(Other definitions for stops that I've seen before include "Halts" , "Ends" , "Prevents" , "Ceases" , "Discontinues" .)
