Definition & Meaning of "klutz"in English

What is the origin of the term "klutz" and how is it used?

"Klutz" is an English slang term borrowed from Yiddish klots, meaning "block of wood" or "clumsy person," which entered American English in the early 20th century. The word metaphorically likens a person to a wooden block—awkward, heavy-handed, or prone to accidents. It describes someone who is clumsy, awkward, or constantly dropping things. The term is commonly used in informal speech in the U.S., often teasingly or humorously, and is mildly derogatory rather than seriously offensive.
