Took care of business in latest mess? Give me that in plain English! (9)
I believe the answer is:
translate
'english' is the definition.
(thesaurus)
'took care of business in latest mess? give me that in plain' is the wordplay.
I cannot quite see how this works, but
'took' could be 'ate' (eating is a kind of taking) and 'ate' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for translate that I've seen before include "make comprehensible" , "shift" , "Ten altars (anag.)" , "Restate in another language" , "Put in other words" .)
