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 before)
'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' says to put letters next to each other.
'out' indicates an anagram (out can mean wrong or inaccurate).
'tea' is an anagram of '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)" .)
