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 really 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 found within the answer.
No letters remain.
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" .)
