presumptuous
UK: prɪˈzʌmptʃuəs | US: prɪˈzʌmptʃuəs
adj. behaving with excessive confidence or boldness, often without proper justification
adj. overstepping appropriate boundaries or norms
The word "presumptuous" originates from Latin praesumptuosus, derived from praesumere ("to take beforehand"). The morpheme "pre-" (before) combines with "sumpt" (from sumere, "to take"), reflecting the idea of acting prematurely or without permission. The suffix "-uous" (adjective-forming) emphasizes the trait of overconfidence. Historically, it evolved through Old French presumptueux before entering Middle English, retaining its core meaning of unjustified boldness.
