What is the origin of word gobsmacked?

The origin of "gobsmacked" is uncertain, but the most widely accepted theory is that it originated in British slang sometime in the mid-20th century.

Here's what we know:

* "Gobsmacked" first appeared in print in 1957. It was used in a short story by British author Alan Sillitoe, suggesting it was already in common use by then.

* The word is likely a combination of "gob" and "smacked." "Gob" is a slang term for mouth, while "smacked" can refer to being hit or stunned.

* The exact meaning of "gobsmacked" is unclear. It seems to have evolved over time, but it generally refers to a state of extreme surprise or shock.

Here are some possible origins:

* "Gob" + "smacked": This suggests a sudden, forceful impact that leaves someone speechless.

* "Gob" + "struck": Another possibility, as "struck" can also mean "amazed" or "stunned."

* "Gob" + "mocked": Less likely, but some suggest it could refer to being so surprised you're left speechless and unable to retort.

It's important to note that no single source definitively confirms the word's origin.

Despite its uncertain origins, "gobsmacked" is a popular and widely used word in English, particularly in British English. It's a lively and expressive term that captures the feeling of being completely taken aback.
