Yhdyssissä
Yhdyssissä is a Finnish term referring to compound words. Compound words are formed by combining two or more existing words to create a new word with a distinct meaning. This is a very common and productive word-formation process in Finnish. The meaning of the compound word is often related to the meanings of its constituent parts, but it can also develop a unique or more specialized meaning. For example, the word "tietokone" (computer) is a compound of "tieto" (knowledge/information) and "kone" (machine).
The structure of Finnish compound words typically involves a genitive or adverbial form of the first word
