Uusilla

Uusilla is a Finnish grammatical form, specifically the adessive plural form of the adjective uusi, meaning "new." In Finnish, adjectives agree with the nouns they modify in number and case, and the adessive case marks location or means. When used with plural nouns, the adessive ending is -illa, producing uusilla. The phrase therefore roughly translates to "on/with the new ones" and is typically used to refer to multiple items that are new relative to a reference point.

Uusilla is not a standalone noun; it is a case-inflected form of uusi. It commonly appears with plural nouns in the adessive case to indicate that someone is using, possessing, or being located with new items. For example, uusilla autoilla means "with the new cars" or "in the new cars," and uusilla vaatteilla means "in the new clothes." The form is frequent in everyday Finnish and in writing, especially when contrasting new versus old items.

Examples:

- Henkilöt pukeutuivat uusilla vaatteilla. (People wore new clothes.)

- Päätös perustui uusilla ideoilla. (The decision was based on new ideas.)

- Lähdimme matkalle uusilla autoilla. (We set off on new cars.)
