nestemäisinä

Nestemäisinä is a Finnish grammatical form that functions as the plural essive of the adjective nestemäinen, meaning liquid. In Finnish grammar, the essive case expresses a temporary state or role, often translated as "as" or "in the capacity of." For adjectives, the essive singular is nestemäisenä, and the essive plural is nestemäisinä. The form is used when several items are described as being in a liquid state.

Formation and use: The plural essive is created from the -inen adjectives by replacing the usual ending to -isina in the plural. Thus nestemäinen becomes nestemäisinä in the essive plural. This contrasts with the singular essive nestemäisenä, which would describe one item in a liquid state.

Examples: These sentences illustrate typical usage. Nämä nesteet ovat nestemäisinä huoneenlämpötilassa. Aineet A, B ja C ovat nestemäisinä tarkasteluhetkellä. In contrast, kiinteänä means solid and kaasuna means gaseous; the plural essive allows a direct comparison of multiple substances in the liquid state alongside other states.

Notes: The essive form is commonly found in scientific, culinary, and descriptive Finnish where state or role is being specified. Nestemäisinä is specifically used for plural subjects; for a single item, nestemäisenä would be used. The construction follows general Finnish rules for -inen adjectives with the essive case.
