In linguistic typology, polysynthetic languages, formerly holophrastic languages, are highly synthetic languages, i.e., languages in which words are composed of many morphemes (word parts that have independent meaning but may or may not be able to stand alone). They are very highly inflected languages. Polysynthetic languages typically have long "sentence-words" such as the Yupik word tuntussuqatarniksaitengqiggtuq.
