inequivoco

Inequivoco, or inequívoco in Spanish and Portuguese, is an adjective meaning unequivocal: clear, certain, and not open to doubt or multiple interpretations. It describes statements, evidence, or conclusions that leave little or no room for ambiguity or dispute.

Etymology: The term derives from Latin aequivocus "ambiguous," with the negating prefix in-, passing into Iberian languages during the influence of Latin and medieval Romance. The masculine form is inequívoco and the feminine inequívoca.

Usage: In law and science, inequívoco describes evidence or results that are beyond reasonable doubt. In philosophy and logic, it denotes propositions or arguments that are unambiguous. In journalism and everyday language, the word signals something presented as clearly true or proven.

Orthography: In both Spanish and Portuguese the word carries an acute accent on í, yielding inequívoco (masc.) and inequívoca (fem.).
