Flibbertigibbet is believed to have originated as a nonsense word, similar to other playful or whimsical words like “gibberish” or “hocus-pocus.” In English, it has been used since the 16th century to describe people who are frivolous, flighty, or talkative. The term is often used in a playful or lighthearted context, and is sometimes considered an old-fashioned or dated word. Today, however, it is still used in a variety of contexts, from literature and journalism to everyday conversation.
