Loup is a term which refers to the Algonquian language varieties spoken in colonial New England as attested in the manuscripts of mid-eighteenth century French missionaries. Loup A was attested in a notebook titled Mots loups, compiled by Jean-Claude Mathevet, a priest who worked among Algonquian peoples, composing of 124 pages. Loup ('Wolf') was a French colonial ethnographic term, and usage was inconsistent. In modern literature, Loup A refers to the varieties described by Mathevet, and Loup B refers to those described by François-Auguste Magon de Terlaye.
