Church is welcoming poor country’s folk (8)
I believe the answer is:
chileans
'church is welcoming poor country's folk' is the definition.
I can't tell whether this defines the answer.
'church is welcoming poor' is the wordplay.
'church' becomes 'ch' (common abbreviation).
'welcoming' is an insertion indicator (in sense of 'inviting in').
'poor' becomes 'lean' ().
'is' enclosing 'lean' is 'ileans'.
'ch'+'ileans'='CHILEANS'
Can you help me to learn more?
(Other definitions for chileans that I've seen before include "countrymen" , "Natives of South America's longest country" , "Natives of Santiago, say" , "people in Santiago" .)
