Cardinal shut a don out (8)

Ross

I believe the answer is:

thousand

'cardinal' is the definition.
(similar in meaning)

'shut a don out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'shut'+'a'+'don'='shutadon'
'shutadon' anagrammed gives 'THOUSAND'.

(Other definitions for thousand that I've seen before include "cube" , "Figure" , "See 1 down" , "Numeric value of kilo" , "M or K" .)

I've seen this clue in The Telegraph.
