Altaissa

Altaissa is a Finnish inessive plural form of the noun allas, meaning basin, pool, or tank. The form expresses location, roughly translating to “in basins” in English. As a grammatical inflection, altaissa shows how Finnish marks plural inessive case, indicating that the subject is located inside multiple basins.

In standard usage, altaissa appears in contexts referring to water containers, such as basins, tanks, or troughs. It is commonly found in scientific, industrial, or culinary descriptions that involve multiple basins or pools, and it fits with verbs and adjectives that align with a plural subject.

Examples:

- Kalat elävät altaissa. (The fish live in the basins.)

- Altaissa on vettä. (There is water in the basins.)

Notes:

- Altaissa is not a standalone lexical item with a meaning beyond the grammatical form; its meaning is derived from the base noun allas and the inessive plural ending.

- Related forms include altaat (nominative plural basins), altaassa (singular inessive “in the basin”), and altaista (plural elative “from the basins”).
