The everyday neurotic definition is someone who is very anxious, tense or fussy, worrying about things far more than the situation needs. If a friend checks the stove five times before leaving and still fears the house will burn down, people might jokingly call that neurotic.
The word began in medicine, where it described a group of mental conditions called neuroses. Doctors no longer use it as a formal diagnosis, but it lives on in casual speech and in personality research, where a related trait called neuroticism is measured.

Neurotic meaning in plain words
In daily English, calling a person neurotic means they worry a lot, overthink, get upset easily or need things done in a very particular way. It often comes with a smile, as in "I'm a bit neurotic about my handwriting", but it can also be a put-down.
- Anxious: fearing the worst about small things.
- Obsessive: checking, rechecking, needing control.
- Emotionally reactive: taking minor setbacks very hard.
To define neurotic in a phrase: nervous and tense beyond what makes sense.
How the neurotic definition shifted over time
The definition of neurotic has moved a long way from its start. William Cullen used neurosis for disorders he believed came from the nervous system. Later, psychiatrists used neurosis for conditions involving distress such as anxiety, phobias or obsessive thoughts, where a person still stays in touch with reality. This was contrasted with psychosis, where contact with reality is affected.
The American psychiatric manual dropped neurosis as a formal category in its third edition in 1980, grouping those conditions under headings such as anxiety disorders instead. The adjective neurotic then drifted further into casual speech. Today a doctor is unlikely to diagnose you as neurotic; a friend might still say it.
Neuroticism as a personality trait
In personality psychology, neuroticism is one of the five broad traits in the widely used Big Five model, alongside openness, conscientiousness, extraversion and agreeableness. A person who scores high tends to feel worry, sadness or irritation more often and more strongly. A low score means more emotional stability.
Researchers stress that this is a scale everyone sits somewhere on, not an illness. Some researchers even prefer the label "emotional stability" for the low end, because neuroticism sounds harsh.

Neurotic, anxious and obsessive compared

| Paranoid | Distrust; believing others mean harm |
| Highly strung | Easily upset or excited, a gentle British phrase |
The word overwhelmed fits a moment of too much pressure, while neurotic suggests a pattern.
Is it polite to say?
Using it about yourself is usually fine and often self-mocking. Using it about someone else can sting, because it suggests their feelings are silly or excessive. Avoid it for people who live with a diagnosed anxiety condition, since it turns a real struggle into a joke. For more words about moods and character, see our people and feelings section.
