adverb 'at first' shows the deceptive quality

Sense: noun/1

Glibness, fluency, smoothness, and superficiality all relate to how someone speaks, but they carry very different tones. Fluency is the most neutral: it simply means the ability to speak easily and smoothly, often in a foreign language, with no implication of dishonesty. Smoothness can be neutral or positive — a smooth presenter comes across as polished and professional. Superficiality focuses on the lack of depth in what is said, but does not necessarily imply a slick or confident delivery. Glibness combines the smooth delivery of fluency with the shallowness of superficiality, and adds a critical edge: a glib person sounds convincing in the moment precisely because they avoid real thought. For example, you would call a car salesperson glib if they gave fast, confident answers that fell apart under scrutiny. A bilingual child, by contrast, is fluent — not glib.

Etymology

Old Low GermanEnglish

Glibness comes from the adjective glib, which entered English from the Old Low German word glibberig, meaning slippery or smooth. The original sense described a smooth, slippery surface, and by the 1600s it was being applied figuratively to speech that was smooth and easy but also evasive — like a surface you cannot get a grip on. The noun form glibness appeared in the 1700s to name that quality directly.
