Every other change neatly arranged (11)

Ross

I believe the answer is:

alternately

'every other' is the definition.
(thesaurus)

'change neatly arranged' is the wordplay.
'change' becomes 'alter' (altering is a kind of changing).
'arranged' indicates an anagram.
'neatly' with letters rearranged gives 'nately'.
'alter'+'nately'='ALTERNATELY'

(Another definition for alternately that I've seen is " In turn".)

I've seen this clue in The Guardian.
