Arouse extremes of utmost ire in a fellow? (9)
I believe the answer is:
infuriate
'arouse extremes of utmost ire in a fellow?' is the definition.
I can't judge whether this defines the answer.
'arouse extremes of utmost ire in a fellow?' is the wordplay.
'arouse' is an anagram indicator (I've seen 'arousing' mean this).
'extremes of' means to remove the middle letters (only the letters at the extremes of the word).
'fellow?' becomes 'f' (abbreviation - of a society etc.).
'utmost' with its middle taken out is 'ut'.
'ut'+'ire'+'in'+'a'+'f'='utireinaf'
'utireinaf' anagrammed gives 'INFURIATE'.
(Other definitions for infuriate that I've seen before include "incense" , "get very warm" , "Enrage or exasperate" , "Make someone very angry" , "anger" .)
