People bragged occasionally about new table ornament (7)
I believe the answer is:
epergne
'table ornament' is the definition.
(I've seen this before)
'people bragged occasionally about new' is the wordplay.
'occasionally' means one should take alternating letters.
'about' indicates putting letters inside.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'people'+'bragged'='peoplebragged'
The alternate letters of 'peoplebragged' are 'eperge'.
'eperge' going around 'n' is 'EPERGNE'.
(Other definitions for epergne that I've seen before include "Large table centerpiece with branching holders" , "table display" , "Ornamental fruit- holding centrepiece for table" , "Table centrepiece with flowers, fruit" , "Stand on table" .)
