iltatyyppii

Iltatyyppii is a coined Finnish term used in informal contexts to describe a person who is most active, social, or productive during the evening hours. The concept reflects popular discussions about chronotypes and nightlife but is not an official or scientific category. As a label, it is typically humorous or self-referential, signaling a preference for evenings over mornings rather than a clinical personality type.

The word is formed from ilta ('evening') and tyyppi ('type' or 'person'). In online writing it is sometimes rendered as iltatyyppii, with an extended final vowel, a stylistic feature common in meme culture and informal Finnish.

Usage appears in social media posts, lifestyle blogs, and discussions about scheduling, productivity, or social life. Because it is informal, its meaning depends on context and it may vary between speakers. Examples: "Olen iltatyyppii ja nautin illan rauhasta" and "Hän on iltatyyppii, joka järjestää illan tapahtumia myöhään." The term tends to overlap with but remains distinct from traditional concepts such as "yökyöpeli" (night owl).

Iltatyyppii is primarily used in online and casual contexts and has limited acceptance in formal Finnish. Related terms include yökyöpeli (night owl) and broader discussions of chronotypes in popular science.
