Sign
A sign is anything that stands for something else to some interpreter, the subject of semiotics. Peirce gave it a triadic structure and Saussure a dyadic one centered on language.

Sign (semiotics): the basic unit of semiotics, standing for something else. Defined dyadically by Saussure (signifier plus signified) and triadically by Peirce (representamen, object, interpretant), with icon, index, and symbol as Peirce's principal classes.

Sign stealing
Sign stealing: decoding an opposing baseball team's signals, chiefly catcher-to-pitcher pitch signs. Legal by naked eye from the field (runner on second), illegal with electronic devices; the 2017 Houston Astros scandal and PitchCom followed.
Sign test
The sign test is a nonparametric statistical test presented by Dixon and Mood in 1946, testing paired differences or a single sample's median using only the signs of the differences.
Sign-on and sign-off
Sign-on and sign-off are the ceremonial broadcast-day opening and closing sequences of radio and TV stations, including test tones, idents, national anthems and closedowns, largely replaced by 24-hour broadcasting but retained as morning formalities.
Signa Holding
Signa Holding is an Innsbruck-based Austrian real estate and retail holding company founded by René Benko, whose 2023 collapse became the largest insolvency in Austrian history.
Signage
Signage: physical signs, symbols, and graphics conveying direction, location, safety, or action in built spaces. Also called sign systems; distinct from wayfinding (a tool within it) and environmental graphic design. Covers signboard history from 1866, ADA tactile and ISO standards, and retail impact data.
Signal
A signal, also called an electrical signal, is a physical quantity conveying information, typically a voltage or current representing another quantity such as sound or temperature.
Signal (IPC)
A signal, known as a Unix or POSIX signal, is a software interrupt notifying a process of an asynchronous event, an IPC mechanism in UNIX-like systems.
Signal (software)
Signal, also known as Signal Private Messenger, is an encrypted messaging app run by the US nonprofit Signal Technology Foundation, founded in 2018 by Moxie Marlinspike and Brian Acton.
Signal (시그널) (South Korean TV series)
Signal (시그널) is a 2016 South Korean fantasy police procedural drama on tvN, starring Lee Je-hoon, Kim Hye-soo, and Cho Jin-woong as detectives linked by a walkie-talkie across time.
Signal AI
Signal AI (Signal Media Ltd.) is a London-based artificial intelligence company founded in 2013 by CEO David Benigson that sells AI-driven reputation and risk intelligence to large enterprises.
Signal amplification
Signal amplification: biological process where small molecular signals produce large responses, and the Reactome pathway R-HSA-392518 in which platelet ADP, ATP, and thromboxane A2 recruit further platelets after vascular injury.
Signal amplification by reversible exchange
Signal amplification by reversible exchange (SABRE) is a nuclear spin hyperpolarization technique that uses parahydrogen to greatly enhance NMR and MRI signals without chemically modifying the substrate.
Signal attenuation
Signal attenuation (Reactome R-HSA-74749) is the insulin receptor signaling shutdown step: endosomal protein tyrosine phosphatases dephosphorylate INSR, IRS1, IRS2, and SHC1, collapsing signaling complexes; endocytosis and receptor degradation attenuate signaling generally.
Signal averaging
Signal averaging is a signal processing technique that averages repeated measurements of a time-locked response so uncorrelated noise cancels, improving the signal-to-noise ratio in EEG, ECG, and spectroscopy.
Signal conditioning
Signal conditioning is the set of electronic techniques that convert a raw sensor output into an amplified, filtered, isolated, and linearized signal suited to measurement, processing, or digitization.
Signal crayfish
Signal crayfish (Pacifastacus leniusculus), a large North American freshwater crayfish native to the Pacific Northwest, introduced across Europe and Japan, carrier of lethal crayfish plague and a major invasive species.
