Taken in charge by a group of police, is sour (6)
I believe the answer is:
acidic
'sour' is the definition.
(similar in meaning)
'taken in charge by a group of police' is the wordplay.
I cannot quite understand how this works, but
'a' is within the answer.
'police' could be 'cid' (abbreviation for Criminal Investigation Department) and 'cid' is found within the answer.
'in charge' could be 'ic' (abbreviation for 'in charge') and 'ic' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'is' is the link.
Can you help me to learn more?
(Other definitions for acidic that I've seen before include "Containing a sour-tasting substance" , "Tart, sour" , "Sarcastic or sour" , "Sharp-tasting, sour" , "Like vinegar" .)
