Täydennettyä

Täydennettyä is a Finnish grammatical form that functions as a participial adjective meaning “supplemented” or “augmented.” It is the partitive singular form of the past passive participle täydennetty, which derives from the verb täydennetä (to supplement, to complete). As a modifier, täydennettyä describes content that has been added to or expanded.

In usage, täydennettyä is typically placed before a noun in partitive case, especially when referring to information, data, or material that has been enhanced. Common examples include täydennettyä tietoa (supplemented information) and täydennettyä dataa (augmented data). The form can also appear in predicative position with a noun in partitive, as in raportti on täydennettyä tietoa (the report contains supplemented information).

Morphologically, the form illustrates Finnish’s participial system, where past passive participles act as adjectives. The partitive singular ending -ä/-ä in täydennettyä signals that the accompanying noun is in partitive, a frequent pattern when discussing non-countable or mass-like content.

Etymology and related forms: täydennettyä comes from täydennetä, with the past passive participle stem täydennet-, plus the adjectival ending. Related terms include täydennys (an addition or supplement) and täydennettävä (to be supplemented).

Notes: Täydennettyä is not a standalone noun; it is a verb-derived form used to qualify nouns. It conveys a completed or augmented state and is common in technical, scientific, and administrative Finnish to describe augmented content.
