Cat seen by bishop in burial place (4)
I believe the answer is:
tomb
'burial place' is the definition.
(I've seen this before)
'cat seen by bishop' is the wordplay.
'cat' becomes 'tom' (a tom is a male cat).
'seen by' means one lot of letters go next to another.
'bishop' becomes 'B' (chess abbreviation).
'tom'+'b'='TOMB'
'in' acts as a link.
(Other definitions for tomb that I've seen before include "Place for the burial of a corpse" , "Mausoleum" , "Burial-vault" , "grave situation" , "Sepulchral monument" .)
