Quick Summary

In linguistics, polysynthesis describes a highly synthetic language where a single word, often a verb, can form an entire sentence by incorporating numerous affixes. These languages, such as Eskimo and many Native American languages, express grammatical relationships through inflection and agglutination.1

Polysynthesis is a characteristic of synthetic languages, which use affixes, vowel alternations, and consonant changes to convey grammatical meaning. While analytic languages rely more on word order and separate words (like prepositions) to show grammatical relationships, synthetic languages integrate these meanings into the words themselves.21
