säkin

Säkin is a Finnish colloquial form used to indicate that the listener is included in a statement, effectively meaning “you too” or “you as well.” It is a contracted variant of sinäkin and is most common in informal speech and in online communication.

The form is built from the informal second-person pronoun sä (you) plus the particle kin (also/too). It mirrors the meaning of the standard sinäkin but fits casual register. It can appear at the start of a sentence or within it: for example, Säkin voit tulla mukaan means “You can come along too.”

Usage and style: Säkin is widely used among younger speakers and in everyday conversation, memes, and social media. It is considered non-standard Finnish, so in formal writing or careful speech, sinäkin or teikin (for plural you) would be preferred. The word is understood across Finnish-speaking regions and is part of the broader pattern of pronoun-plus-kin constructions found in colloquial Finnish.

See also: The standard form sinäkin, which expresses the same meaning in formal or written Finnish, and other colloquial variants of kin with different pronouns (tekin, mekin). Säkin shares its function with these constructions as a way to include the audience or acknowledge their involvement.
