Dad clutching an idol in temple (6)
I believe the answer is:
pagoda
'temple' is the definition.
(pagoda is a kind of temple)
'dad clutching an idol' is the wordplay.
'dad' becomes 'pa' ('pa' can be a synonym of 'dad').
'clutching' is an insertion indicator.
'an' becomes 'a'.
'idol' becomes 'god' ('god' can be a synonym of 'idol').
'a'+'god'='agod'
'pa' enclosing 'agod' is 'PAGODA'.
'in' acts as a link.
(Other definitions for pagoda that I've seen before include "Hindu/Buddhist temple" , "Pyramid-shaped Asian temple" , "temple? Quite the opposite" , "Buddhist memorial building" , "religious structure" .)
