Outcry as golfer's warning covers only half the quartet (6)
I believe the answer is:
furore
'outcry' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'golfer's warning covers only half the quartet' is the wordplay.
'golfer's warning' becomes 'fore' (I've seen this in another clue).
'covers' means one lot of letters goes inside another.
'only half' suggests halving the letters.
'the quartet' becomes 'four' (synonyms).
'four' halved is 'ur'.
'fore' placed around 'ur' is 'FURORE'.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for furore that I've seen before include "Uproar, hullabaloo" , "Storm" , "Turmoil, uproar" , "Uproar, outcry" , "agitation" .)
