Definition
Meaning

This is a compound noun (noun + noun). It is a fixed expression describing a personal characteristic. It is often used in self-description or informal comparison. While related to the concept of a 'night owl,' it is slightly more neutral and descriptive of a general disposition rather than just staying up late.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque like 'ночной человек.' The standard translation is 'сова' (night owl) or the descriptive phrase 'человек, который поздно ложится и поздно встаёт.' 'Ночной человек' might be misunderstood as a creature of the night or a suspicious character.
Common Mistakes
- Using 'night' as an adjective alone (*He is very night). Forgetting the article 'a' (*I am night person). Confusing with 'night shift worker' (which is a job, not necessarily a preference).
