Figure important, though not the first (6)
I believe the answer is:
eighty
'figure' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for eighty that I've seen before include "Four score" , "Cardinal" , "Fourscore" , "Northern county (abbr.)" , "22 [FOUR] scores" .)
