Is male supporting article's religious belief? (6)
I believe the answer is:
theism
'religious belief?' is the definition.
(I know that theism is a type of religious belief)
'is male supporting article's' is the wordplay.
'male' becomes 'm' (common abbreviation).
'supporting' is a charade indicator (letters next to each other) (in a down clue, some letters go below others).
'article' becomes 'the' (the definite article in English).
'is'+'m'='ism'
'ism' after 'the' is 'THEISM'.
(Other definitions for theism that I've seen before include "Belief in a creator" , "The doctrine or belief in the existence of a God or gods" , "Belief in existence of a God revealed to man" , "Belief in a deity" , "of faith" .)
