Origin (Theories)

There is no single confirmed origin, but several long‑standing theories explain how the phrase likely developed:

1   Folkloric / Punitive Theory (Most Cited)

One theory links the phrase to corporal punishment, where a whip known as a cat‑o’‑nine‑tails was used.  The idea is that, metaphorically, if someone struck into silence had their “tongue taken” by the cat.  While evocative, historians note there is no direct documentary proof tying the phrase to this practice.

2   Ancient Superstition Theory

Another theory traces it to ancient Egypt, where cats were sacred and believed to have power over speech or the afterlife. According to folklore, liars could have their tongues cut out and fed to a ca s. This explanation is colorful but largely mythic rather than evidentiary.

3.  Simple Metaphor Theory (Most Linguistically Likely)

The most accepted explanation among linguists is that it’s simply a humorous metaphor:

• Cats are quick, sneaky, and associated with mischief.
• Imagining a cat stealing someone’s tongue creates a vivid image explaining silence.

This aligns with many English idioms that rely on absurd imagery rather than literal History.

Historical Usage

• The phrase appeared in English print by the late 1800s
• It became common in British and American English in the early 20th century
• It remains widely used today in casual conversation

Bottom Line
