Piano or piece of furniture easy to carry (8)
I believe the answer is:
portable
'easy to carry' is the definition.
'piano or piece of furniture' is the wordplay.
'piano' becomes 'p'.
'piece of furniture' becomes 'table' (table is a kind of piece of furniture).
'p'+'or'+'table'='PORTABLE'
(Other definitions for portable that I've seen before include "radio" , "Handy - lightweight" , "Laptop, for example" , "to take with you" , "Light enough to carry" .)
