Religious area set up in church yard? That’s rather corny (6)
I believe the answer is:
cheesy
'rather corny' is the definition.
'religious area set up in church yard?' is the wordplay.
'religious area' becomes 'see' (a 'see' is the location of a cathedral).
'set up' shows that the letters should be reversed in order.
'in' means one lot of letters goes inside another.
'church' becomes 'ch' (common abbreviation).
'yard?' becomes 'y'.
'see' written backwards gives 'ees'.
'ch'+'y'='chy'
'ees' placed into 'chy' is 'CHEESY'.
'that's' is the link.
(Other definitions for cheesy that I've seen before include "like others on the board?" , "characteristic of a fondue?" , "Like Cheshire (Cat's grin?)" , "Hackneyed, trite" , "showing poor taste" .)
