Part of church left for contemplation (5)
I believe the answer is:
navel
'for contemplation' is the definition.
(I've seen this before)
'part of church left' is the wordplay.
'part of church' becomes 'nave' (area of a church building).
'left' becomes 'l' (common abbreviation).
'nave'+'l'='NAVEL'
(Other definitions for navel that I've seen before include "Variety of orange" , "Part of body; sort of orange" , "for contemplation" , "Umbilicus" , "Belly button" .)
