What does idled mean?
Idled is the past tense and past participle of idle. It most often describes a person spending time without working, studying, or making useful progress, although the expression is neutral rather than necessarily critical: someone may have idled because no task was available or because deliberate inactivity was reasonable. With a vehicle, machine, or engine, idled refers to remaining or being kept running without doing productive work. The form can also appear before a noun, as in “an idled engine,” where it indicates that the engine was left running. Idled is common in both British and American English and is equally applicable in formal reporting and informal conversation. It is useful because it captures two related ideas: inactivity by people and unnecessary or nonproductive operation by machinery.
To spend time doing nothing or making no productive progress; to operate or remain running without doing useful work.
"The motor idled for several minutes before the driver accelerated."
The meaning depends on the subject: with a person it denotes inactivity, while with a machine or engine it denotes running without productive work.
Describing a machine or engine that has been allowed to run or remain running without doing productive work.
"The idled engine overheated while the driver waited."
This is a participial adjective, normally placed before a noun.
Before “idling” described a lazy person, “idle” meant empty, worthless, or vain.
