polysynthetic language
Definition - A synthetic language that has an extremely high morpheme-to-word ratio. These types of languages often have very long words that correspond to what would be complete sentences in English.

For example, in the Eastern Siberian language Chukchi, the word Temeyngelevtpe╬│terken means "I have a fierce headache."

Etymology -
The term was probably first used by Peter Stephen DuPonceau in 1819 to describe American languages. It was made popular in a posthumously published work by Wilhelm von Humboldt (1836). However, it was first used in its modern sense by Edward Sapir in the 1920s.
