A not-too-serious sin (6)

I believe the answer is:

venial

'a not-too-serious sin' is the definition.
(I've seen this before)

This is the entire clue.

(Other definitions for venial that I've seen before include "A not-too-serious sin" , "Excusable" , "offering excuse" , "Slight and pardonable (sin)" , "An evil (anag) - easily excused" .)

I've seen this clue in The Irish Times and the Irish Times (Simplex).
