negare

Negare is a verb with primary senses to deny, refuse, or repudiate. It is attested in Classical Latin as negāre and is the source of several related terms in modern languages. In English and other Romance languages, the verb and its cognates have given rise to words such as negate and negation.

The etymology traces to Latin negāre, from the Proto-Italic root *neǵ- indicating negation or denial. Cognate forms appear in Romance languages, notably Italian negare, Spanish negar, and French nier, reflecting a common concept of denial across languages.

In Italian, negare is a regular -are verb meaning to deny. Its present tense forms include nego, neghi, nega, negiamo, negate, negano; the corresponding noun for the act is negazione. The term is used in everyday speech as well as in legal, political, and media contexts.

In philosophy and formal logic, negation (negatio in Latin) is the operator that inverts the truth value of a proposition. It is symbolized by not or ¬ in many languages and plays a central role in reasoning, mathematics, and computer science.
