Control credit somehow (6)
I believe the answer is:
direct
'control' is the definition.
(I know that direct is a more specific form of the action care)
'credit somehow' is the wordplay.
'somehow' is an anagram indicator.
'credit' with letters rearranged gives 'DIRECT'.
(Other definitions for direct that I've seen before include "'Straight, without deviation (6)'" , "Control the affairs" , "Regulate" , "Outspoken" , "Control, supervise" .)
