Tavallisissa

Tavallisissa is the plural inessive form of the Finnish adjective tavallinen, meaning ordinary or common. It is used with plural nouns in the inessive case to describe beings, things, or situations that are considered ordinary or typical. The form can also appear in elliptical or context-driven sentences where the noun is understood from prior context.

Grammar and usage notes:

- The base adjective tavallinen governs agreement with the noun it modifies. In the inessive plural the ending is -issa, yielding tavallisissa.

- Typical phrases include tavallisissa oloissa (in ordinary circumstances) and tavallisissa tapauksissa (in ordinary cases). The form helps contrast normal conditions with exceptional or unusual ones.

- While tavallisissa usually accompanies an explicit noun, it can sometimes appear without the noun in contexts where the reference is clear from previous discourse, especially in formal or literary Finnish.

Examples:

- Tavallisissa oloissa järjestelmä toimii odotetusti. (Under ordinary conditions, the system works as expected.)

- Tavallisissa tapauksissa tutkimus antaa selviä tuloksia. (In ordinary cases, the study yields clear results.)

Relation to other forms:

- Tavallisen/tavallista are used for singular contexts, with corresponding case endings. Tavallisissa serves specifically plural inessive usage, while other cases produce forms like tavallisin, tavallisessa, or tavallisiin depending on number and case.

Tavallisissa thus functions as a practical, commonly used inflection for describing ordinary plural entities or conditions in Finnish prose.
