Expert writing Tips

Best practice

Employ the phrase when you want to introduce a potentially great idea while simultaneously downplaying its initial importance to avoid sounding overconfident.

Common error

Do not use "idle thought" as a synonym for a "stupid" or "unintelligent" idea. An "idle thought" can be brilliant or profound; the term describes how the thought arrived (without effort) rather than its inherent quality. For a thought that lacks sense, use terms like "nonsense" or "absurd notion".

Linguistic Context

The phrase "idle thought" functions primarily as a noun phrase composed of the attributive adjective "idle" and the common noun "thought". It typically serves as the subject or direct object of a sentence. According to Ludwig, it is often paired with verbs of motion or emergence such as "crossed my mind" or "popped into".
