Bring up a matter of higher wages (5)
I believe the answer is:
raise
'bring' is the definition.
(thesaurus)
'up a matter of higher wages' is the wordplay.
I cannot really understand how this works, but
'up' could be 'is' (I've seen this in other clues) and 'is' is found within the answer.
'a' is within the answer.
'matter' could be 're' (Re is an example) and 're' is found in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for raise that I've seen before include "Make greater" , "Heighten" , "climb" , "cairn" , "Bring up; levy" .)
