According to "Steven A. Jacobson's (1984) Yup'ik Eskimo dictionary",
Inuit languages have about15 "lexemes (independent noun vocabulary
items or dictionary entries) for snow. Eskimo languages are
inflectionally so complicated that each single noun lexeme may have
about 280 distinct inflected forms, while each verb lexeme may have
over 1000.
