Force people to show elegance (5)
I believe the answer is:
grace
'elegance' is the definition.
(I've seen this before)
'force people' is the wordplay.
'force' becomes 'g' (short for gravity).
'people' becomes 'race' (people can mean a national group or race).
'g'+'race'='GRACE'
'to show' acts as a link.
(Other definitions for grace that I've seen before include "Before dinner, one may have this" , "34 [CRICKETER]" , "Elegance; girl's name" , "Honour" , "beauty of movement" .)
