Definition & Meaning of "dang"in English

What is the origin of the exclamation "dang" and how is it used?

Dang is an exclamation used to express surprise, frustration, or admiration in a mild way. It appeared in American English in the 19th century as a softened euphemism for "damn," following a long tradition of lightening strong swear words.
