Cupboard love, camp poet inspired (9)
I believe the answer is:
sideboard
'cupboard' is the definition.
(thesaurus)
'love camp poet inspired' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'camp' becomes 'side' (both can mean a group or faction).
'poet' becomes 'bard' (bard is a kind of poet).
'inspired' means one lot of letters goes inside another (inserted letters have been inspired or breathed in).
'side'+'bard'='sidebard'
'o' inserted inside 'sidebard' is 'SIDEBOARD'.
(Other definitions for sideboard that I've seen before include "Piece of dining-room furniture" , "Dior beads (anag.)" , "Item of dining-room furniture" , "Dining room furniture" , "dresser?" .)
