'False Alarm' Meaning and Example Sentences

The idiom "false alarm" is a phrase used to describe a situation where an alarm or warning is sounded, but there is no actual danger or emergency present. It is usually used as a noun phrase, but can also be used as an adjective phrase (e.g. "false alarm signal").

The origin of the phrase is believed to come from the use of alarm systems in buildings or homes, where a false alarm would occur when the alarm was triggered by something other than a real emergency or danger. This phrase has been used since the early 20th century.

The phrase can be used in a variety of contexts, but is commonly used to describe a situation where someone mistakenly believes there is danger or emergency present, when in fact there is not. It can also be used in a more general sense to describe any situation where something is thought to be true or happening, but turns out to be false.

It's important to note that the idiom false alarm has a negative connotation. It implies a sense of disappointment, wasted energy, and possibly even frustration. As such, it's mostly used in situations where it's clear that no real danger was present, or it was clear that the alarm was not real.
