Pagan ignores one kind (6)
I believe the answer is:
gentle
'kind' is the definition.
(I've seen this before)
'pagan ignores one' is the wordplay.
'pagan' becomes 'gentile' ('gentile' can be a synonym of 'pagan').
'ignores' is a deletion indicator.
'one' becomes 'i' (Roman numeral).
'gentile' with 'i' removed is 'GENTLE'.
(Other definitions for gentle that I've seen before include "Moderate in effect" , "Jane Eyre's kind person with a book? -- eternal greed (anag)" , "Moderate, quiet; a maggot" , "Mild, not rough" , "Kind-natured" .)
