fourth-class
Lowest postal category
Fourth-class designates the lowest tier in a ranking system, typically implying inferior quality or status.
In the U.S. postal system, fourth-class mail historically referred to parcels and printed matter—the slowest and cheapest category.
More broadly, fourth-class describes anything relegated to the bottom: fourth-class accommodations, treated like a fourth-class citizen.
