So far, the man has taken tea out (2,4)
I believe the answer is:
to date
'so far' is the definition.
(I've seen this in another clue)
'the man has taken tea out' is the wordplay.
'the man has' becomes 'tod' (I am not sure about this - if you are sure you should believe this answer much more).
'taken' is a charade indicator (letters next to each other).
'out' is an anagram indicator (out can mean wrong or inaccurate).
'tea' with letters rearranged gives 'ate'.
'tod'+'ate'='TO DATE'
Can you help me to learn more?
(Other definitions for to date that I've seen before include "Until this point in time" , "Up to this time - check calendar" , "Reason suitor's come" , "Thus far" , "Up to the present time (2.4)" .)
