Grating, tactile dancing (7)
I believe the answer is:
lattice
'grating' is the definition.
(thesaurus)
'tactile dancing' is the wordplay.
'dancing' indicates an anagram.
'tactile' anagrammed gives 'LATTICE'.
(Other definitions for lattice that I've seen before include "Openwork structure" , "Web" , "Fretwork, grille" , "Framework in diagonal pattern" , "grill" .)
