• Early Assamese
• Middle Assamese

Assamese (plural Assameses or Assamese)

1. (chiefly in the plural) A member of the people of Assam.

As with other terms for people formed with -ese, the countable singular noun in reference to a person (as in "I am an Assamese", "writing about Assamese cuisine as an Assamese") is uncommon and often taken as incorrect. In its place, the adjective is used, by itself (as in "I am Assamese") or before a noun like person, man, or woman ("writing about Assamese cuisine as an Assamese person"). See also -ish, which is similarly only used primarily as an adjective or as a plural noun.
