Suffiikki

Suffiikki is a term used in linguistics to describe a suffix, which is a morpheme that is attached to the end of a word. Suffixes modify the meaning or grammatical function of the base word. For example, in English, the suffix "-ing" can be added to verbs to form participles or gerunds, such as in "running" or "swimming." The suffix "-ed" is used to indicate the past tense of many verbs, as in "walked."

Suffixes can indicate a variety of grammatical information, including tense, number, gender, case, and mood. They can also be used to create new words with different meanings or grammatical categories, such as turning a verb into a noun or an adjective into an adverb. For instance, the suffix "-ness" in English often forms abstract nouns from adjectives, as seen in "kindness" from "kind." The suffix "-ly" typically converts adjectives into adverbs, as in "quickly" from "quick."

The function and form of suffixes vary greatly across languages. Some languages have a rich system of suffixes, while others use them sparingly or rely on other grammatical devices. The study of suffixes is a fundamental part of morphology, the branch of linguistics concerned with the structure of words. Understanding suffixes helps in analyzing word formation, deciphering the meaning of unfamiliar words, and understanding the grammatical structure of sentences.
