Each dart shot bit of light into place of worship (9)
I believe the answer is:
cathedral
'place of worship' is the definition.
(cathedral is a kind of place of worship)
'each dart shot bit of light' is the wordplay.
'shot' is an anagram indicator.
'bit of' suggests taking the first letters.
The first letter of 'light' is 'l'.
'each'+'dart'='eachdart'
'eachdart' anagrammed gives 'cathedra'.
'cathedra'+'l'='CATHEDRAL'
'into' acts as a link.
(Other definitions for cathedral that I've seen before include "religious building" , "religious site" , "Principal Christian church in a diocese" , "St Paul's or St Patrick's" , "Bishop's seat" .)
