Venial is an adjective that means slight or pardonable.
The word venia (VEN ee uh) is Latin for forgiveness. Our word of the day is pretty much always used to refer to a sin or mistake. A venial sin is one that can be forgiven. A mortal sin, on the other hand, cannot.
The cook badly burned my pork chops last Thursday. But, as it was a venial sin, I let the matter slide.
