millaisilla

Millaisilla is a Finnish grammatical form used as part of the interrogative adjective millainen, meaning “what kind of.” It is the adessive plural form that describes plural nouns in the sense of “with what kinds of” or “on what kinds of.” In Finnish, adjectives decline to agree with the noun in number and case, so millainen changes across singular and plural and into different cases; millaisilla is specifically used when the modified noun is plural and in the adessive case.

Formation and use: millainen is the base meaning “what kind of.” To form millaisilla, the stem is inflected for the adessive case and plural number, yielding the form that accompanies plural nouns in sentences such as “millaisilla välineillä” (with what kinds of tools) or “millaisilla ehdoilla” (on what kinds of terms/conditions). This construction is common in questions, descriptions, and comparative or evaluative statements that involve multiple items.

Examples:

- Millaisilla välineillä teimme tutkimuksen? (With what kinds of tools did we perform the study?)

- Millaisilla ehdoilla sovimme kumppanuudesta? (On what kinds of terms did we agree to a partnership?)

- Millaisilla keinoilla ongelma ratkaistaan? (By what kinds of means will the problem be solved?)

Relation to other forms: The corresponding singular adessive form is millaisella (singular), and the nominative plural would be millaiset. The form fits within Finnish adjective and determiner inflection patterns and is a standard element in language description and Finnish grammar resources.
