Advantage of rearranging seats? (5)
I believe the answer is:
asset
'advantage' is the definition.
(I've seen this before)
'rearranging seats?' is the wordplay.
'rearranging' indicates anagramming the letters (I've seen 'rearranged' mean this).
'seats' anagrammed gives 'ASSET'.
'of' acts as a link.
(Other definitions for asset that I've seen before include "Something valuable to have" , "Part of motor vehicle wheel" , "Resource; advantage" , "- - -stripper" , "Something useful" .)
