Figure out meal run (7)
I believe the answer is:
numeral
'figure' is the definition.
(thesaurus)
'out meal run' is the wordplay.
'out' indicates an anagram.
'meal'+'run'='mealrun'
'mealrun' is an anagram of 'NUMERAL'.
(Other definitions for numeral that I've seen before include "Figure or symbol like '1', for example" , "Counting symbol" , "Figure representing an integer" , "Such as 5, 9, iii, etc" , "1, 2, 3, for instance" .)
