An agglutinative language is a type of language where words are formed by stringing together different morphemes, each representing a distinct meaning or grammatical function. In agglutinative languages, these morphemes are added to a root word without changing the original form, creating complex words with multiple affixes. Each affix typically has a specific meaning, such as tense, case, gender, or number. Examples of agglutinative languages include Turkish, Finnish, Japanese, and Swahili. These languages allow for the creation of new words and convey intricate meanings through the systematic addition of affixes to the root words.
