'counting' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'one element of not' is the wordplay.
'one' becomes 'a' (a thing is one thing).
'element' becomes 'part' (a segment or piece).
'of not' becomes 'from' (I can't justify this - if you can you should believe this answer much more).
'a'+'part'+'from'='APART FROM'
