Religious law would harm anyone to some extent (6)
I believe the answer is:
dharma
'religious law' is the definition.
'dharma' can be an answer for 'law' (I've seen this before). I'm unsure of the 'religious' bit.
'would harm anyone to some extent' is the wordplay.
'to some extent' indicates the answer is hidden within the clue.
'DHARMA' is hidden in the letters of 'would harm anyone'.
Can you help me to learn more?
(Other definitions for dharma that I've seen before include "Eternal law of the cosmos (Indian religion)" , "Hindu eternal law" , "Buddhist truth; am hard (anag.)" , "Cosmic law (in Indian religion)" .)
