Tables etc initially required, not included in future (9)
I believe the answer is:
furniture
'tables etc' is the definition.
(table is a type of item of furniture)
'initially required not included in future' is the wordplay.
'initially' indicates taking the first letters.
'in' is an insertion indicator.
The initial letters of 'required not included' is 'rni'.
'rni' going into 'future' is 'FURNITURE'.
(Other definitions for furniture that I've seen before include "Cabinet?" , "Room furnishings" , "Tables, chairs, beds etc" , "Accessories" .)
