<p>A bayou is not a bog, it is a bayou. It is sort of a swamp, and sort of a wetland and sort of an inlet, but not exactly any of those, but is a well-known term to anyone who lives in Mississippi, Louisiana, or who has read any Faulkner or Tennessee Williams.</p>
<p>Both bard and bayou are words that pop up in normal intelligent conversation in many part of the US.</p>
