The phrase “runt of the litter” is a common English expression used to describe the smallest or weakest animal in a group of siblings born at the same time. The word runt traditionally refers to an unusually small animal, while litter means a group of young animals born to the same mother during one birth. So, the runt of the litter is literally the smallest animal among its brothers and sisters.
However, the expression is also used figuratively when talking about people, organizations, teams or things. In this broader sense, it can describe someone or something that is smaller, weaker, less successful or less impressive than the others in the same group. Because of this figurative meaning, the phrase can sometimes sound insulting or dismissive, depending on the context. Understanding both its literal and figurative meanings will help you use it naturally and appropriately.

“Runt of the litter” means the smallest or weakest member of a group of animals born at the same time. Figuratively, it can describe a person or thing that is smaller, weaker or less successful than the other members of its group.
Why Do People Say “Runt of the Litter”?
The expression comes from animal breeding.
A litter is a group of young animals born to the same mother at approximately the same time, especially puppies, kittens, pigs or similar animals.
A runt is the unusually small or weak member of that group.

What Does “Runt” Mean?

For example:
