liitsufiksist
The term "liitsufiksist" is not a recognized linguistic term in standard Estonian or any other language. It appears to be a misspelling or a fabricated word. In linguistics, suffixes are morphemes that are attached to the end of a word to modify its meaning or grammatical function. For example, in Estonian, the plural suffix "-d" is added to nouns like "maja" (house) to form "majad" (houses). Similarly, the possessive suffix "-i" is used to indicate ownership, such as in "majaomanik" (house owner).
