Customer looking angry with the insurance? (7)
I believe the answer is:
covered
'customer looking' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
'angry with the insurance?' is the wordplay.
'angry' becomes 'red' (someone may go red when angry).
'with' means one lot of letters go next to another.
'the insurance?' becomes 'cove' (I can't justify this - if you can you should give a lot more credence to this answer).
'red' put after 'cove' is 'COVERED'.
Can you help me to learn more?
(Other definitions for covered that I've seen before include "Concealed; roofed over" , "Insured; enveloped" , "Concealed; dealt with" , "Reported" , "Overlaid with something" .)
