Yhdistetyillä

Yhdistetyillä is a Finnish inflected form, specifically the adessive plural of the past participle yhdistetty (meaning "combined" or "merged"). As an adessive case form, yhdistetyillä typically conveys meanings equivalent to English prepositions such as "with," "on," or "at" when applied to multiple items (for example, "with the combined data" or "on the combined networks").

Grammatical role and formation: yhdistetyillä is formed from the verb yhdistää ("to combine") → past participle yhdistetty → adessive plural yhdistetyillä. It is used when referring to several entities described as combined and indicating location, possession, means, or accompaniment (adessive functions).

Usage examples:

- Yhdistetyillä tiedoilla analyysi paranee. (With the combined data, the analysis improves.)

- Yhdistetyillä alueilla palvelut ovat saavutettavampia. (In the combined areas, services are more accessible.)

Context and meaning: The form appears in written and spoken Finnish in administrative, technical, and everyday contexts where multiple items have been merged or grouped. Its exact meaning depends on context and the noun it modifies; it can indicate physical location, instrumental use, or association.

Related forms include yhdistetty (nom./sg./pl.), yhdistetyt (nom. pl.), and other case forms such as yhdistetyissä (inessive plural). As an inflectional variant, yhdistetyillä is not a lexical headword but a grammatical form of yhdistetty.
