Fetor is a noun that refers to a strong, foul smell. 

Our word of the day comes directly from the Latin word for ‘soul smell.’ It’s been around since the 17th century and is used to describe foul smells that have been around much longer. Example:

The fetor coming from the parking lot dumpster became such a distraction that we had to move it. Rotten smells aren’t exactly the kind of things you want customers to be exposed to after leaving a restaurant.
