In literature, "glib" is frequently used to denote a kind of smooth, facile speech that, while charming on the surface, often lacks genuine substance or emotional depth. Authors employ the term to describe characters who deliver their words with mechanical ease or even insincerity—as when a speaker casually unleashes calumnies with a glib flourish [1] or when a character’s polished repartee masks ulterior motives [2]. The word can carry ironic connotations, highlighting an artful yet superficial eloquence, as seen in depictions of orators whose persuasive, glib discourse betrays a calculated charm [3], or in satirical portrayals that contrast the fluent talk of a charismatic rogue with the expectation of deeper sincerity [4]. In this way, "glib" becomes a versatile literary device that underscores the tension between slick verbal dexterity and authentic communication.
