North or South, state the facts about a knockout (6)
I believe the answer is:
dakota
'north or south state' is the definition.
(I've seen this in another clue)
'facts about a knockout' is the wordplay.
'facts' becomes 'data' (data are bits of information).
'about' indicates putting letters inside.
'a knockout' becomes 'KO' (abbreviation).
'data' enclosing 'ko' is 'DAKOTA'.
'the' acts as a link.
(Other definitions for dakota that I've seen before include "Native Americans" , "US territory split North and South" , "old aircraft" , "State < facts about completely stunning" , "Mass-produced transport plane, WWII workhorse, the DC-3" .)
