Relating to, characteristic of, or involving barratry; fraudulent or criminal in nature, especially regarding maritime conduct.
From barratry plus -ous suffix (full of, characterized by). The adjective form standardizes the sense of 'involving fraud' or 'constituting barratry'.
The word 'barratrous' is so rare that most English speakers have never encountered it, yet it's technically the proper adjective form—proof that not all grammatically valid words survive everyday use!
