Etymology

The compound "nice guy" is a relatively modern formation, emerging in the 20th century. Its logic is transparent, directly combining the adjective "nice," which evolved from a Latin term for "ignorant" through a semantic journey to mean "precise" and then "agreeable," with the noun "guy," a slang term for a man derived from the historical figure Guy Fawkes. The term's modern, often ironically tinged meaning—a man whose pleasantness is seen as a passive or unassertive trait—developed through cultural usage, particularly in discussions of dating and interpersonal dynamics. It represents a case where a literal descriptive phrase acquires a specific, nuanced connotation within a social context.
