kirjaudua

Kirjaudua is a Finnish verb form that is used to express the action of signing in or logging in to a digital service. In standard Finnish, the more common infinitives and variants for this action are kirjautua or kirjaudu, and they appear in most user interfaces and formal writing. Kirjaudua, by comparison, is not widely attested as a primary standard form and is often regarded as nonstandard, regional, or a variant spelling encountered in specific texts or informal speech.

In usage, kirjaudua may appear alongside other related forms of the same verb family, which centers on entering a system or service. The concept captured by kirjaudua is the same as logging in, authenticating, or gaining access to a protected area of a website or application. The form is typically understood in contexts where readers recognize it as a form of the broader kirjautua/kirjautua paradigm, even though it is less common in contemporary standard Finnish.

Linguistically, kirjaudua belongs to Finnish verbs that express a process related to an entry or registration, built from the root associated with entry or inscription and standard Finnish verb suffixes. The term functions semantically like other login-related verbs, but speakers should prefer established forms such as kirjautua or kirjaudu in formal writing and official documentation.
