Queen covered by favourite band is more than fair (8)
I believe the answer is:
prettier
'more than fair' is the definition.
I can't tell whether this definition defines the answer.
'queen covered by favourite band' is the wordplay.
'queen' becomes 'r' (abbreviation for regina, e.g. in ER ).
'covered by' indicates putting letters inside.
'favourite' becomes 'pet' (synonyms).
'band' becomes 'tier' (I've seen this before).
'r' placed within 'pet' is 'pret'.
'pret'+'tier'='PRETTIER'
'is' is the link.
Can you help me to learn more?
(Other definitions for prettier that I've seen before include "More lovely" , "More attractive in a delicate way" , "More beautiful" .)
