Definition & Meaning of "deadbeat"in English

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

"Deadbeat" is an American slang term that appeared in the late 19th century, originally referring to someone who failed to pay debts. The word combines "dead," suggesting complete absence or failure, with "beat," possibly from slang for being worn out or defeated, to imply someone who does not meet obligations. Over time, its meaning broadened to describe a lazy, irresponsible, or unreliable person who avoids work or duties, such as a parent who does not provide support. It is used in informal speech and media, often critically, and is clearly derogatory, targeting a person's behavior and character rather than being vulgar.
