Can phone fellow in advance to get carpet, say (8)
I believe the answer is:
flooring
'carpet say' is the definition.
(carpet is a type of flooring)
'can phone fellow in advance' is the wordplay.
'can' becomes 'loo' (both can informally mean toilet).
'phone' becomes 'ring' (synonyms).
'fellow' becomes 'F' (abbreviation - of a society etc.).
'in advance' means one lot of letters go next to another.
'loo'+'ring'='looring'
'looring' after 'f' is 'FLOORING'.
'to get' acts as a link.
(Other definitions for flooring that I've seen before include "Carpet, wood, etc." , "Material for walking on" , "Bewildering" , "Baffling completely, knocking down" , "platform" .)
