A religious symbol in clues like this (6)
I believe the answer is:
across
'clues like this' is the definition.
(I've seen this before)
'a religious symbol' is the wordplay.
'religious symbol' becomes 'cross' (Christian symbol).
'a'+'cross'='ACROSS'
'in' is the link.
(Other definitions for across that I've seen before include "14 of these clues are" , "Towards the other side of" , "Clue with solution not going in the direction of this one!" , "Traversing" , "From side to side, like this clue" .)
