What does timer mean?
A timer is chiefly a device that measures elapsed time or counts down a set interval, often signaling when the period has ended. It may be a kitchen or countdown timer, a timer used by software to trigger an action, or a person responsible for timing a race. In ordinary speech, “timer” is neutral and practical rather than highly technical. The verb “to timer” is much less common, chiefly informal American usage, and means to time something; “time” itself is usually the more natural choice. The word's usefulness lies in its specificity: it names an instrument, mechanism, or official devoted to measuring duration. It also recalls the practical origins of such devices and the central human concern with keeping track of elapsed time. Whether used at the stove, in a race, or inside a computer program, a timer turns the abstract passage of time into a measurable interval and a clear endpoint.
A device that measures elapsed time or counts down a specified interval, often signaling when the interval has ended; also, a person or mechanism responsible for timing.
"The timer sounded before the tea had finished steeping."
The noun is common in domestic, sporting, technical, and computing contexts. It may denote a physical device, a software mechanism, or, less commonly, a race official.
To time an event, activity, or competitor by measuring its duration.
"Officials timered each heat with a handheld stopwatch."
This use is informal and chiefly North American. The ordinary verb “time” is normally preferred in formal writing.
The standard plural is used for multiple timing devices, software timers, or people serving as timekeepers.
"The coaches placed timers beside each running track."
A timer can be the person, the device, or the software mechanism—either way, its job is to make elapsed time countable.

Where does timer come from?
Timer is an English formation from time with the productive suffix -er, denoting a person or thing that times or measures time. Time comes through Old English tīma, which belongs to a Germanic word family and is generally traced farther back to Latin tempus. Related English words such as timely, temporary, and contemporary reflect the Latin tempor- root, which also underlies tempor- formations in several other languages.
