The phrase Runt of the Litter describes the smallest and weakest person in a group, especially among siblings, with a clear meaning. It comes from newborn mammals, where a runt is the smallest baby in a litter at birth. Because of its size and weakness, it is considered the least likely to thrive or survive, although the expression is now also used for someone who is physically smaller or less strong than others.
In a family, a child or sibling may jokingly be called the runt, especially if a middle child has a younger sister who is taller and sometimes picks on them. From my experience, the phrase is usually playful, and its meaning depends on the situation, the relationship, and the people involved rather than being a serious insult.
Nature shows that many newborn animals overcome early challenges through growth and improve their survival. The same idea applies to people because someone at the bottom of the social hierarchy can still succeed and thrive with confidence, effort, and support.
Quick Answer

- It originally refers to the smallest or weakest baby animal born in a group.

What Does “Runt of the Litter” Mean?
A runt of the litter is the smallest or weakest young animal born with its brothers and sisters.
For example, if a dog gives birth to six puppies, one puppy may be much smaller than the others. That puppy is called the runt of the litter.
Over time, people started using this expression for humans and other situations too.
For example:
- The smallest player on the basketball team.
- The weakest company in a group.
- The least successful product in a business.
The phrase does not always mean someone will stay weak forever. Many stories show the runt becoming stronger and more successful later.
The Origin of the Phrase
The phrase comes from farming and animal breeding.
Animals such as:
- Dogs
- Cats
- Pigs
- Rabbits
- Wolves
often give birth to several babies at one time. This group of babies is called a litter.
Sometimes one baby is much smaller than the others because it received less food before birth or had a slower start. Farmers called this baby the runt.
As the years passed, English speakers began using the phrase as an idiom for anything that seemed smaller, weaker, or less important than the rest.
