Every year, install a deity inside temple (6)
I believe the answer is:
pagoda
'temple' is the definition.
(pagoda is a kind of temple)
'every year install a deity' is the wordplay.
'every year' becomes 'pa' (per annum).
'install' indicates putting letters inside.
'deity' becomes 'god' (a deity is a god or divine being).
'a'+'god'='agod'
'pa' placed around 'agod' is 'PAGODA'.
'inside' is the link.
(Other definitions for pagoda that I've seen before include "religious structure" , "Eastern building" , "Sacred many-tiered temple" , "Oriental temple, often a tower" , "Buddhist tower with several stories" .)
