Street grooves seen in parades (6)
I believe the answer is:
struts
'parades' is the definition.
(I've seen this in another clue)
'street grooves' is the wordplay.
'street' becomes 'st' (abbreviation).
'grooves' becomes 'ruts' ('rut' can be a synonym of 'groove').
'st'+'ruts'='STRUTS'
'seen in' acts as a link.
(Other definitions for struts that I've seen before include "Swaggers" , "parades with conscious pride" , "arrogant motions" , "Bars inserted into framework to strengthen it" , "Walks in proud, showy way" .)
