Syn. -- Irreproachable; sinless; unblemished; inculpable. -- 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. [ 1913 Webster ]

adv. In a blameless manner. [ 1913 Webster ]

n. The quality or state of being blameless; innocence. [ 1913 Webster ]
