impecable

Impeccable is an adjective meaning faultless, flawless, or of the highest standard. It is used to describe performance, appearance, behavior, or quality that is free from noticeable defects. Common collocations include impeccable timing, impeccable manners, impeccable service, and an impeccable reputation.

The word has its roots in Latin impeccabilis, literally “not sinning,” from in- “not” + peccare “to sin,” and entered English through the influence of Old French and later stages of Middle English. Over time, it came to indicate purity of quality rather than moral perfection.

Usage notes: Impeccable emphasizes high quality and exacting standards. It is not synonymous with unimpeachable; the latter means beyond question or beyond doubt, especially in terms of credibility, whereas impeccable focuses on excellence of form or behavior. Both adjectives are positive but carry different nuance.

Common errors: In English, the correct spelling is impeccable with two p’s; "impecable" is generally a misspelling in English. However, impecable exists in other languages (for example Spanish impecable) with the same meaning.

Examples: The chef's impeccable technique impressed even seasoned critics. The hotel earned an impeccable rating for cleanliness and service.
