ärataja

Ärataja is a Finnish term that translates to "awakener" or "alarm clock" in English. It refers to a device or person that rouses someone from sleep. Historically, this role was often filled by individuals known as "knocker-uppers" or "knockers" in some cultures, who were employed to wake people up at a designated time, typically before the advent of mechanical alarm clocks. These individuals would use tools like long sticks to tap on windows or doors.

In modern usage, ärataja almost exclusively refers to a mechanical or electronic device designed to produce an audible signal at a set time to wake a person. The most common form is the bedside alarm clock, which can be analog or digital. These devices have become ubiquitous in households worldwide. More advanced iterations are integrated into smartphones and other personal electronic devices, offering a wide range of alarm sounds, customization options, and even gradual wake-up features that simulate sunrise. The primary function remains the same: to ensure timely awakening for daily routines, appointments, and responsibilities.
