lisäsuffixes

A lisäsuffix is a suffix in the Finnish language that is added to a noun, pronoun, or adjective to indicate possession or belonging. These suffixes are attached to the end of the word and change its form to show that something belongs to someone or something. For example, the suffix -ni is added to a noun to indicate first-person singular possession, so "talo" (house) becomes "taloni" (my house). Similarly, the suffix -si indicates second-person singular possession, turning "talo" into "talosi" (your house).

There are distinct lisäsuffixes for each grammatical person (first, second, and third person) and for both singular and plural forms. For instance, the third-person singular possessive suffix is often -nsa or -nsä, depending on vowel harmony, as in "talonsa" (his/her/its house). The plural forms also have their own suffixes. These suffixes are crucial for expressing ownership and relationships clearly in Finnish. They are an integral part of Finnish grammar and contribute to the language's agglutinative nature, where multiple morphemes are attached to a base word. Understanding and correctly using lisäsuffixes is essential for fluent Finnish communication.
