A floor covering containing black and white? (6)
I believe the answer is:
albino
'white?' is the definition.
(thesaurus)
'a floor covering containing black' is the wordplay.
'floor covering' becomes 'lino' (short for linoleum).
'containing' indicates putting letters inside.
'black' becomes 'b' (as in pencil classifications).
'lino' placed around 'b' is 'lbino'.
'a'+'lbino'='ALBINO'
'and' acts as a link.
(Other definitions for albino that I've seen before include "Abnormally white animal - on Bali (anag)" , "Feel" , "Colourless character" , "Lacking normal skin pigment" , "Animal or plant lacking pigmentation" .)
