Testeillä

Testeillä is a Finnish noun form meaning “on the tests” or “at the tests.” It is the plural adessive form of testi, the noun for test. In Finnish, the adessive case marks location or placement and uses the ending -llä in the singular and -llä in the plural. Therefore, testeillä literally translates to “on the tests” or “at the tests,” while the singular form is testillä (on the test). The corresponding nominative plural is testit, and other cases for related meanings include testeihin (into the tests) and testeissä (in the tests).

Grammatical overview: testi (singular nominative); testit (plural nominative); testillä (singular adessive); testeillä (plural adessive). The form testeillä adheres to Finnish noun declension patterns for -i nouns, where the stem vowel and consonant changes reflect the plural adessive ending.

Usage: testeillä appears in contexts where multiple tests are located, performed, or being discussed as a group. It is common in educational, scientific, or software testing documentation and reporting, especially when referring to tests gathered at a site or in a testing environment.

Notes: Finnish grammar relies on postposed case endings to express spatial relations, so testeillä functions as a location indicator for a plural set of tests. As with other Finnish forms, stress is typically on the first syllable.
