Aremus is dog in indian language
The likely word is the proper noun Aramis (one of the Three Musketeers, also a fragrance name).The term aremus is used to mean dog in the Penobscot Amerindian language, as used in the novel The Sign of the Beaver (1983).
As used in the fictional novel The Sign of the Beaver (1983), it means dog.
The fake unspecified native word aremus (and its fake translation: "dog") can be found in only one place - a children's fictional story titled The Sign of the Beaver by Elizabeth George Speare. Speare was a noted author of children's stories with absolutely no credentials as a linguist or student of native American culture or languages. She invented the entire thing.Children's books are not generally the place to find genuine native American languages or customs - it's like expecting to learn accurate history from Bugs Bunny cartoons.
