Sign

A sign is a means of communication using written or spoken language, visual graphics, or symbols that conveys information, instructions, or warnings. In its broadest sense, a sign can be any object, quality, event, or entity that conveys meaning. The term "sign" is derived from the Latin word signum, which means a mark, token, or indication. In Hebrew, the word for sign is אות (ot), which can also mean a letter or a signal. In other languages, the word for sign includes Zeichen in German, signo in Spanish and Italian, signe in French, and signo in Portuguese. Signs can be categorized into various types, such as road signs, traffic signs, warning signs, and informational signs, each serving a specific purpose in guiding, informing, or alerting people. The study of signs and symbols, known as semiotics, explores how meaning is created and interpreted through different forms of communication.

Sign
A sign is an object, quality, event, or entity whose presence or occurrence indicates the probable presence or occurrence of something else. A natural sign bears a causal relation to its object—for instance, thunder is a sign of storm, or medical symptoms a sign of disease. A conventional sign signifies by agreement, as a full stop signifies the end of a sentence; similarly the words and expressions of a language, as well as bodily gestures, can be regarded as signs, expressing particular meanings. The physical objects most commonly referred to as signs generally inform or instruct using written text, symbols, pictures or a combination of these.
