Meal arranged on new piece of furniture is terrible (10)
I believe the answer is:
lamentable
'terrible' is the definition.
(thesaurus)
'meal arranged on new piece of furniture' is the wordplay.
'arranged' is an anagram indicator.
'on' is a charade indicator (letters next to each other).
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'piece of furniture' becomes 'table' (table is a kind of piece of furniture).
'meal' with letters rearranged gives 'lame'.
'lame'+'n'+'table'='LAMENTABLE'
'is' is the link.
(Other definitions for lamentable that I've seen before include "Awful" , "Pitiful" , "Sorry" , "Deplorable, regrettable" .)
