PERT
Her pert response to the professor’s question made the whole class chuckle.
Fun Fact
“Pert” once meant “clever” in Middle English but evolved to describe liveliness with a hint of sass. A “pert nose” is small and upturned, while a “pert remark” has just enough spunk to be amusing, not offensive.
glib
(adjective) Fluent and confident in speech, but shallow, insincere, or lacking thought.
His glib explanation sounded convincing, but it crumbled under basic questioning.
Mid 17th century: probably from Low German glibberig, meaning “slippery.”
Fun Fact
Glib is often used to describe people who are too quick with their words—especially when it feels rehearsed, dismissive, or disingenuous. Think of sales pitches that sound slick but empty, or politicians who talk around the truth with practiced ease. It’s not a compliment—glibness suggests style over substance, and the listener often walks away feeling talked at, not to.
