The term 'bayou boat' refers to a type of vessel commonly used in the southern United States, particularly in Louisiana. The term can be broken down into four parts: 'eves' (4 letters), 'CAJUN' (5 letters), 'BATEAU' (6 letters), and 'INLET' (5 letters). Eves is a term for the curved edges of a boat's hull, while CAJUN is a term for the culture of French-speaking people who live in Louisiana. BATEAU is a French word for boat, and INLET is a term for a small body of water that connects to a larger body of water. Together, these four words describe a type of boat that is common in the bayous of Louisiana.
