Figure provided by the house vendor (5)
I believe the answer is:
seven
'figure' is the definition.
(I know that seven is a type of figure)
'provided by the house vendor' is the wordplay.
'provided by' indicates a hidden word (the answer is provided within the clue).
'SEVEN' is hidden in the letters of 'the house vendor'.
(Other definitions for seven that I've seen before include "Figure of dwarfs?" , "So many ages of man (AYLI)" , "- Against Thebes (Aeschylus)" , "Cardinal" , "Wonders of the World - Deadly Sins" .)
