Stop working to phone one close to apoplexy about wrong data (4,2,1,3)
I believe the answer is:
call it a day
'stop working' is the definition.
'phone one close to apoplexy about wrong data' is the wordplay.
'phone one' becomes 'calli' (I am not sure about this - if you are sure you should believe this answer much more).
'close to' suggests the final letters (the 'close' to the word).
'about' is an insertion indicator.
'wrong' is an anagram indicator.
The last letter of 'apoplexy' is 'y'.
'calli'+'y'='calliy'
'data' anagrammed gives 'tada'.
'calliy' placed around 'tada' is 'CALL IT A DAY'.
'to' is the link.
Can you help me to learn more?
(Other definitions for call it a day that I've seen before include "Decide to stop doing something" , "pack up" , "Set the style for a 24-hour period" , "sign off" , "announce decision to quit" .)
