Morphologically, languages are characterized along two dimensions.

• The first dimension is the number of morphemes per word. For example, isolation languages (Vietnamese and Cantonese) where each word has one morpheme, and polysynthetic languages ( Siberian Yupik aka Eskimo) where a word can correspond to an entire English sentence.
• The second dimension is the degree in which morphemes are segmentable. For example, agglutinative languages (Turkish) where morphemes have clear boundaries, and fusion languages (Russian) where a single affix may conflate multiple morphemes.
