isuuspäätteellä

Isuuspäätteellä is a Finnish term that translates to "with a suffix" or "as a suffix". It refers to the process of adding a grammatical suffix to a word in the Finnish language. Finnish is an agglutinative language, meaning that suffixes are extensively used to express grammatical functions such as case, possession, number, and tense. These suffixes are attached to the stem of a word, often undergoing sound changes to harmonize with the stem.

For example, the word "talo" (house) can be modified with various suffixes. Adding the genitive case suffix "-n" results in "talon" (of the house). The plural suffix "-t" makes it "talot" (houses), and combining it with the inessive case suffix "-ssa" yields "taloissa" (in the houses). The correct suffix to use depends on the specific grammatical context, including the case, number, and person of the noun, as well as the verb tense and mood in a sentence.

Understanding how suffixes work is crucial for comprehending and producing grammatically correct Finnish. The system of suffixes, while complex, allows for precise expression of relationships between words in a sentence without the need for many prepositions or articles common in other languages. The term "isuuspäätteellä" emphasizes this fundamental aspect of Finnish morphology.
