kirjauduin

Kirjauduin is the first-person singular past tense form of the Finnish verb kirjautua, meaning to log in or sign in to a digital service. It is used to describe that the speaker entered a system at a previous time, such as a website, app, or computer account.

Etymology and meaning: The verb kirjautua is built from the concept of entry or registration, extending the idea of keeping a record into the realm of digital access. The form kirjauduin is created by adding the personal ending -in to the verb stem kirjaudu- (the present stem is kirjaudu-). The word is closely related to nouns such as kirjautuminen (logging in, sign-in) and to the process of authentication.

Conjugation and usage: The past tense forms follow standard Finnish conjugation for a common-class verb. For example: minä kirjauduin, sinä kirjauduit, hän kirjautui, me kirjauduimme, te kirjauduitte, he kirjautuivat. In practice, kirjauduin is commonly used in informal and formal contexts alike when recounting a previous login event. It frequently appears with further context, such as the service or time: “Eilen kirjauduin sisään verkkopalveluun.”

Context and nuance: Kirjaudu- is specifically about signing into an account or system, as opposed to “kirjata” or other register-related terms. The related noun kirjautuminen refers to the act or process of logging in, while sisäänkirjautuminen is another common formulation for sign-in.
