täydentä

Täydentää is a Finnish verb meaning to complete something by adding missing parts or information, i.e., to supplement or make more complete. It is used for documents, data, statements, plans, and other content that requires additional material to reach completeness.

The verb is transitive and typically appears with a direct object such as lomake, raportti, tieto, tai lausunto. In usage, it emphasizes filling gaps, correcting deficiencies, or enhancing accuracy by providing new information. Examples include filling in a form, supplementing a report with new details, or revised statements in light of additional data.

Form and related words: täydennetty, täydennys, täydennysmitta, and täydennysosa are common derivatives. The root katu “täysi” means full, and the suffix -entää creates verbs that express causing something to become full or complete. Related concepts include täydennys (a supplement or addition) and täydentäjä (a supplementer, though more typically used in metaphorical senses).

Usage notes: täytyy erottua from simply lisääminen (adding) in that täydentäminen specifically denotes making something more complete or accurate by providing missing elements, not only adding new items. In academic, administrative, and publishing contexts, täydennys and täydentäminen appear in references to updates, corrections, or expansions of existing material.

In summary, täydentää denotes the act of completing or augmenting by supplying missing or additional information, with common applications in forms, reports, statements, and published works.
