signor

Signor is the Italian honorific used to address or refer to a man, comparable to Mr. or Sir in English. It commonly precedes a surname in formal address, as in Signor Rossi, or is used in direct address in speech, for example, Buongiorno, Signor Rossi.

Etymology and related forms: Signor derives from the Latin senior, meaning elder. The term belongs to a family of Italian titles that also includes Signora (Mrs./Ms.) and Signorina (Miss). The plural form used for multiple men is Signori. The noun form Signore exists as well, meaning “the gentleman,” and is used in broader or more formal contexts.

Usage in modern Italian: In formal writing and introductions, Signor is attached to a surname or used in phrases such as Gentile Signor Rossi (Dear Mr. Rossi). In everyday speech, speakers may opt for first names or the pronoun Lei for politeness rather than repeatedly using the title. Signor is most commonly encountered in business, ceremonial, or traditional settings, while casual conversations often rely on first names.

Variations and related terms: The feminine equivalents are Signora and Signorina, used for women. The plural Signori refers to a group of men (gentlemen) and can appear in formal salutes such as Signore e Signori (Ladies and Gentlemen). The term Signore is a related noun form and is sometimes seen in formal addresses or announcements, distinct from the titular use Signor before a surname.
