Hairy fly in red cordial (8)
I believe the answer is:
friendly
'cordial' is the definition.
(similar in meaning)
'hairy fly in red' is the wordplay.
'fly in red' anagrams to 'FRIENDLY'.
Though, I am unsure how this is indicated.
Can you help me to learn more?
(Other definitions for friendly that I've seen before include "Sociable" , "One is obviously on good terms with" , "prepared to talk to fellow passengers?" , "Kind, pleasant" , "Well-disposed" .)
