ticker
UK: ˈtɪkə | US: ˈtɪkər
n. a device that makes a ticking sound (e.g., a clock or timer)
n. a display showing real-time financial market data (short for "stock ticker")
n. informal term for a heart (from the sound of a heartbeat)
The word "ticker" originates from the verb "tick," imitating the sound of a light, repetitive click (like a clock or heartbeat). The suffix "-er" transforms it into a noun referring to a device or object that produces such a sound. By the late 19th century, "ticker" became slang for the telegraphic stock price printer, which made ticking noises while printing. The term later extended metaphorically to the heart due to its rhythmic pulsing sound.
