Esattezza

Esattezza is an Italian noun that denotes accuracy, correctness, or exactness. In everyday language it describes how closely something corresponds to the truth or to a standard. In technical or scientific contexts, esattezza is used to convey the idea of closeness to a true value, though Italian often distinguishes esattezza from accuratezza and precisione. The related adjective esatto means exact or precise.

Etymology and scope: Esattezza derives from esatto, which itself comes from Latin exactus, meaning made correct or precise. The term sits among several related notions, with accuratezza (accuracy) and precisione (precision) frequently appearing in professional jargon. The exact nuance can vary by field, but esattezza generally emphasizes adherence to a correct or true value.

Usage in language and measurement: In mathematical, scientific, and data contexts, esattezza refers to how near a result is to the true value. It relates to bias and error sources, where high esattezza implies minimal systematic deviation from the truth. Precisione, by contrast, concerns repeatability and consistency across measurements. In everyday Italian, esattezza can simply express correctness or exactness in statements, descriptions, or procedures.

Domains of application: In philosophy and logic, esattezza can describe the exactness of an argument or deduction. In education, journalism, and technical writing, esattezza is valued as clarity, factual correctness, and faithful representation of information. Overall, esattezza serves as a versatile term for the quality of being true, exact, or correctly stated across diverse contexts.
