esatte

Esatte is an Italian adjective meaning "exact" or "precise." In Italian grammar, esatte is the feminine plural form of esatto, used to agree with feminine plural nouns, as in scienze esatte (exact sciences) or misurazioni esatte (precise measurements). The masculine plural form is esatti, used with masculine plural nouns, for example numeri esatti. The word derives from Latin exactus through exactus, meaning drawn tight or precise. In contemporary Italian it is widely used across domains such as mathematics, science, measurement, linguistics, philosophy, and everyday language to indicate a lack of approximation. Phrases like dato esatto (exact datum) and risultato esatto (exact result) are common.

In science, the term scienze esatte historically denotes disciplines that rely on quantitative analysis and precise models, typically including mathematics, physics, chemistry, and computer science. The label is sometimes contrasted with other branches of knowledge that are considered less exact, such as the human sciences, though such distinctions are more historical than strict.

As a word, esatte forms part of a broader family including esattezza, the noun for exactness or precision. Esattezza is used in contexts describing quality of accuracy, and common collocations include con esattezza (with exactness). The term also has cognates in other Romance languages, such as French exact, Spanish exacto, and Portuguese exata, all sharing a common Latin root and similar meanings.

Overall, esatte expresses a value judgment of precision and correctness in language, measurement, and scientific modeling, and remains a standard descriptor in Italian for things that are not approximate.
