Man rule out figure? (7)
I believe the answer is:
numeral
'figure?' is the definition.
(I've seen this before)
'man rule out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'man'+'rule'='manrule'
'manrule' anagrammed gives 'NUMERAL'.
(Other definitions for numeral that I've seen before include "Figure or symbol like '1', for example" , "1, 2, 3, say" , "Rule man (anag) - digit" , "Affable and sociable" , "Symbol used to express quantity" .)
