sometimes followed by of.

17.

Syn: Irreproachable; sinless; unblemished; inculpable.

Usage: {Blameless}, {Spotless}, {Faultless}, {Stainless}. We
speak of a thing as blameless when it is free from
blame, or the just imputation of fault; as, a
blameless life or character. The others are stronger.
We speak of a thing as faultless, stainless, or
spotless, only when we mean that it is absolutely
without fault or blemish; as, a spotless or stainless
reputation; a faultless course of conduct. The last
three words apply only to the general character, while
blameless may be used in reverence to particular
points; as, in this transaction he was wholly
blameless. We also apply faultless to personal
appearance; as, a faultless figure; which can not be
done in respect to any of the other words.
