niggle

A niggle is not a big problem. It is more like a tiny pebble in your shoe that you cannot ignore for long. It is a small but steady feeling of annoyance, discomfort, or worry that stays with you, even when it seems unimportant. Maybe the way a coworker clicks their pen is a little niggle, or maybe a small detail about a weekend plan keeps bothering you in the back of your mind.

Think of it as an itch you cannot quite reach. It may not hurt, but it keeps pulling your attention away. You can also use "niggle" as a verb: a thought might "niggle at" you, meaning it keeps bothering you. A writer might have a niggle about a sentence, feeling that it is not quite right even if they cannot yet explain why.

The word niggle describes a small but persistent source of annoyance, doubt, or physical discomfort. It is not a major crisis. Instead, it is the kind of minor irritation that refuses to go away. Unlike a serious problem that demands immediate action, a niggle is something you may try to ignore, yet it keeps coming back into your thoughts or stays noticeable in your body.

The word is often used for those small things that are hard to shake off. You might have a niggle of doubt about a decision, a niggle of concern about whether you forgot something, or a niggling feeling that a plan is not quite right. In sports and health contexts, a niggle can also be a very minor injury or ache, such as slight muscle tightness, that is not severe but still affects comfort or performance.

You can use "niggle" as both a noun and a verb. As a noun, it is the irritation itself: "A little niggle of doubt crept into her mind." As a verb, it describes the act of bothering in a small but repeated way: "The error in the report niggled at him all evening." The idea behind the word is usually the same in every case: something small, not dramatic, but persistent enough that you keep noticing it. It is the sort of thing you wish would simply disappear so you could get on with your day.
