Number moved there (5)
I believe the answer is:
three
'number' is the definition.
(three is a number)
'moved there' is the wordplay.
'moved' indicates an anagram.
'there' anagrammed gives 'THREE'.
(Other definitions for three that I've seen before include "Sixth root of seven hundred and twenty nine" , "Number constituting a crowd?" , "Square root of nine" , "A crowd, you might say" , "There (anag.)" .)
