The unread, after gin cocktail, love to yell (8)
I believe the answer is:
ignorant
'the unread' is the definition.
(thesaurus)
'gin cocktail love to yell' is the wordplay.
'cocktail' indicates anagramming the letters.
'love' becomes 'o' (love means zero in tennis).
'to yell' becomes 'rant' (I am not sure about this - if you are sure you should believe this answer much more).
'gin' anagrammed gives 'ign'.
'ign'+'o'+'rant'='IGNORANT'
'after' acts as a link.
Can you help me to learn more?
(Other definitions for ignorant that I've seen before include "No rating (anag) - in the dark" , "Lacking knowledge in Tir na nOg" , "Ill-mannered" , "Without knowledge" , "not read" .)
