cohosh

The word 'cohosh' entered English in the late 18th century as a borrowing from Eastern Algonquian languages, where a term similar to 'kewáhsh' or 'kowáh' referred to a rough, medicinal plant. European settlers and herbalists adopted the name specifically for North American plants of the Actaea genus, valued by Indigenous peoples for their therapeutic properties, particularly for women's health. The term's journey from a specific Algonquian descriptor to a standardized common name in herbal pharmacopeia exemplifies the direct borrowing of indigenous knowledge and terminology. Its status as an unanalyzable simplex in English underscores its origin as a loanword adopted for its referent rather than its morphological components.

This word is a simplex loanword from an Algonquian language (likely Eastern Abenaki or Penobscot). It does not contain meaningful, separable morphemes within the English spelling system.
