What does “denim” mean?
Denim is a strong, tightly woven cotton fabric with a diagonal ribbing called a twill weave. It is known for its durability, which is why it was first favored for hard-working clothes.
Traditional denim is woven with an indigo-dyed thread in one direction and a plain, undyed thread in the other. That combination gives denim its familiar blue outside and paler inside. Today, denim comes in many shades, weights and stretch blends.
Because denim is a material, you can find it in many products. Jackets, skirts, shirts, handbags and even sofa upholstery can all be denim. As a fabric name, “denim” is uncountable, so you say “denim is durable,” not “denims are durable.”
What does “jeans” mean?
Jeans are casual trousers, usually made from denim. They are a garment, which means you can wear them, fold them and count them.
The classic style has five pockets and metal rivets at stress points. The riveted version is credited to Jacob Davis and Levi Strauss, who patented the idea in 1873. Since then, jeans have appeared in countless cuts, from skinny to wide-leg.
“Jeans” is a plural-only noun, much like “scissors” or “trousers.” You wear “a pair of jeans,” and you say “these jeans are comfortable.”
Are all jeans made of denim?
Most jeans are made of denim, but a pair of jeans is not always strictly denim. Some trousers shaped like jeans use other fabrics, such as corduroy or stretch twill.
In everyday talk, though, people assume that jeans means denim trousers. If you want to be precise about the material, say “denim jeans.” If you mean a different fabric, name it, as in “corduroy jeans.”
Is it “jean” or “jeans”?
Use “jeans” when you mean the trousers. The singular “jean” appears mainly before another noun, as in “jean jacket” or “jean shorts.”
A common slip is saying “a jeans” when you mean one pair. Write “a pair of jeans” or “some jeans” instead.
Where do the words denim and jeans come from?
Both words are commonly traced to European place names. “Denim” is usually linked to the French phrase serge de Nîmes, meaning a sturdy fabric from the city of Nîmes.
“Jeans” is commonly linked to Genoa in Italy, where a similar cotton twill was made. These origin stories are widely repeated, though the exact details of fabric history can be debated.
Denim vs Jeans: How Can You Remember Which One to Use?
Ask whether you are talking about the cloth or the clothing. If you can wear it as trousers, say “jeans.” If you mean the material itself, say “denim.”
Here is a simple test. Try replacing the word with “trousers.” If the sentence still works, use “jeans.” If it sounds odd, like “a trousers jacket,” you probably mean “denim.”
