temerarious

Temerarious is an adjective describing actions or persons that show excessive boldness without regard for danger or consequences. It implies rashness, impetuosity, or foolhardy risk-taking, and is generally used with negative connotations to criticize a plan or behavior that disregards prudent caution.

Etymology: The word derives from Latin temerarius “rash, reckless,” from temere “rashly, blindly.” It entered English in the early modern period, likely through influence from Latin or French, and has appeared in literary and formal prose since.

Usage: Temerarious is more formal or literary than everyday synonyms such as reckless or rash. It can describe a choice, a plan, or a person whose approach lacks due deliberation. It is often reserved for evaluative statements by writers, editors, or speakers assessing risk or judgment.

Synonyms and related terms: Synonyms include reckless, rash, foolhardy, impetuous, and audacious. Related nouns include temerity (boldness or audacity) and foolhardiness. Antonyms include prudent, cautious, wary, and circumspect.

Examples: The temerarious march into enemy lines endangered the entire unit. Her temerarious investment strategy collapsed when markets shifted, illustrating the dangers of acting without due diligence.
