Shabby clothes Parisian friend spread on the floor (6)
I believe the answer is:
tatami
'spread on the floor' is the definition.
The definition suggests a singular noun which matches the answer.
'shabby clothes parisian friend' is the wordplay.
'shabby clothes' becomes 'tat'.
'parisian friend' becomes 'ami' (I've seen this before. I am not sure about the 'parisian' bit.).
'tat'+'ami'='TATAMI'
Can you help me to learn more?
(Other definitions for tatami that I've seen before include "Japanese rush and straw matting" , "Japanese straw mat; a mat, it (anag.)" , "Floor-covering" , "Jap. floor mat" , "Jap. room matting" .)
