Positive votes won't ultimately provide the reason for an uprising? (5)
I believe the answer is:
yeast
'the reason for an uprising?' is the definition.
I can't tell whether this defines the answer.
'positive votes won't ultimately' is the wordplay.
'positive votes' becomes 'yeas' (I've seen this in another clue).
'ultimately' says to take the final letters.
The final letter of 'wont' is 't'.
'yeas'+'t'='YEAST'
'provide' is the link.
Can you help me to learn more?
(Other definitions for yeast that I've seen before include "Brewer" , "It's put in to raise" , "As yet (anag)" , "Organism causing fermentation" , "Fungus; food supplement" .)
