Ask, was it correct symbol? (8)
I believe the answer is:
swastika
'symbol?' is the definition.
(swastika is a kind of symbol)
'ask was it correct' is the wordplay.
'correct' indicates anagramming the letters (I've seen 'corrected' mean this).
'ask'+'was'+'it'='askwasit'
'askwasit' with letters rearranged gives 'SWASTIKA'.
(Other definitions for swastika that I've seen before include "Cross with its arms bent at right angles in a clockwise direction" , "Adopted badge of the former German Nazi Party" , "Mark of evil" , "Nazi symbol (somewhat resembling this crossword grid!)" , "Emblem of the Nazi Party" .)
