yllätyksille

Yllätyksille is a Finnish noun phrase that functions as the allative plural form of yllätys, meaning "surprise." It is used to refer to the recipient of a surprise or to describe situations and activities that are intended to involve surprises for several people.

Grammatically, yllätyksille is formed by adding the allative plural suffix -ille to the noun yllätys.
