Bring up the question of a pay increase (5)
I believe the answer is:
raise
I believe this clue is a quadruple definition!!
'bring' is the first definition.
(thesaurus)
'up' is the second definition.
(thesaurus)
'the question' is the third definition.
(thesaurus)
'of' acts as a link.
'a pay increase' is the fourth definition.
(Other definitions for raise that I've seen before include "More money from America" , "Advance" , "Bring up, rear" , "Make greater" , "cairn" .)
