Etymology
the word 'impeccably' has a direct lineage from latin, built upon the verb 'peccare', which meant "to stumble, to err, or to sin". the prefix 'im-' (a form of 'in-') negates this root, creating the sense of "not sinning" or "without fault". this concept was adopted into english via the french 'impeccable', carrying the secularized meaning of "flawless". the addition of the adverbial suffix '-ly' transforms the adjective into its current form, describing an action performed in a manner that is completely free from error or imperfection.
