Floor covering Lionel unrolled with some hesitation (8)
I believe the answer is:
linoleum
'floor covering' is the definition.
(I've seen this before)
'lionel unrolled with some hesitation' is the wordplay.
'unrolled' indicates anagramming the letters.
'with' says to put letters next to each other.
'some hesitation' becomes 'um' (**).
'lionel' anagrammed gives 'linole'.
'linole'+'um'='LINOLEUM'
(Other definitions for linoleum that I've seen before include "Impregnated fabric for the floor" , "Mule/lion cross for a floor covering" , "Stiff floor covering" , "Kind of floor covering with shiny surface" , "Common floor covering, often in kitchen" .)
