Tietokoneesi

Tietokoneesi is the Finnish possessive form meaning “your computer.” It is formed from tietokone, the standard Finnish word for a computer, itself a compound of tieto (“information”) and kone (“machine”), plus the second-person singular possessive suffix -si. The result is a noun phrase that clearly refers to the computer belonging to the person being spoken to.

Grammatically, tietokoneesi denotes ownership by a single, informal listener. For formal or plural “your,” Finnish typically uses tietokoneenne or teidän tietokoneenne. The suffix -si attaches to the base form of tietokone, and the word is used wherever “your computer” would appear, as in Kytke tietokoneesi päälle (“Turn on your computer”).

In everyday language, tietokoneesi is common in instructions, guides, and conversations about personal devices. It is not a separate noun but a possessive form of tietokone that expresses ownership. The same possessive suffix pattern can be used with other nouns, for example ohjelmistosi (“your software”) or tietokoneenne (“your computers” or, in formal address, “your computer”). The form is a standard part of Finnish possessive grammar and reflects how ownership is encoded directly on the noun.
