täydennetä

Täydennetä is a Finnish non-finite verb form that appears as the passive infinitive of the verb täydenentää (to complete, to supplement). In Finnish grammar, the passive infinitive is used in formal or impersonal constructions to indicate that an action should be or can be performed on the subject, without naming the agent. The form translates roughly to “to be completed” or “to be supplemented” in English.

Usage and occurrence in language

Täydennetä primarily occurs in formal, bureaucratic, or instructional contexts such as manuals, regulations, and procedural texts. It often appears with implied subjects or in impersonal statements, where the focus is on the action rather than who performs it. For example, a guideline might say that certain information “täydennetä,” meaning it is to be completed or provided. Because it is a non-finite form, täydennetä is typically embedded within larger clauses and can combine with auxiliary expressions to indicate timing or obligation.

Morphology and related forms

The form is derived from the verb täydennetää/täydentää (to complete, to supplement) and shows Finnish vowel harmony and finite-inflection patterns typical of passive infinitives. Related forms in the same verb family include the active infinitive (täydentää), the finite passive (täydennetään, “it is completed”), and participial variants used to express completed or ongoing actions.
