Row about rite (4)
I believe the answer is:
tier
'row' is the definition.
(a tier is a row of things)
'about rite' is the wordplay.
'about' indicates an anagram.
'rite' is an anagram of 'TIER'.
(Other definitions for tier that I've seen before include "Level of a structure" , "Rank - order" , "Rank, level" , "he hasn't won?" , "Wedding cake feature" .)
