In every family, classroom, or workplace, there’s often that one person who stands out — the one who doesn’t quite fit the mold. That’s the black sheep. This colorful idiom describes someone who’s different from the rest, usually in ways that raise eyebrows. In this post, we’ll explore the meaning, origin, and everyday examples of “a black sheep.”
Meaning of “A Black Sheep”
The idiom “a black sheep” refers to a person who is considered the odd one out in a group — especially in a family. Traditionally, it carries a negative tone, describing someone who brings embarrassment, shame, or simply doesn’t conform to expectations.
Main meanings:
- 
Someone whose behavior or choices are disapproved of by their family or group. 
- 
A person who stands out for being different — not necessarily in a bad way. 
In short:
A black sheep is the member of a group who doesn’t fit in with the rest, often viewed as a disappointment or outsider.
Origin of “A Black Sheep”
The expression “a black sheep” dates back to the 18th century in England. It comes from actual black sheep in flocks — animals that were considered undesirable because their dark wool couldn’t be dyed and matched the others. Since black wool was less valuable, shepherds saw black sheep as “bad luck” or “worth less.”
Over time, the phrase evolved from describing literal sheep to labeling people who didn’t fit in or who brought shame to their family or community. Interestingly, some modern thinkers have flipped the meaning — seeing the black sheep as a symbol of individuality and courage to be different.
