Decide not to proceed with the visit? (4,3)
I believe the answer is:
call off
'decide' is the definition.
Although both the answer and definition are verbs in their base form, I can't understand how one could define the other.
'not to proceed with the visit?' is the wordplay.
'not to proceed' becomes 'off' (I can't explain this - if you can you should give a lot more credence to this answer).
'with' is a charade indicator (letters next to each other).
'the visit?' becomes 'call' (call is a kind of visit).
'off' put after 'call' is 'CALL OFF'.
Can you help me to learn more?
(Other definitions for call off that I've seen before include "Abandon" , "Cancel - summon away" , "Cancel as with match - shout it?" , "Cancel, order not to proceed" , "Order to desist" .)
