What does denim mean?
Denim is a tough, hard-wearing cotton fabric woven in a twill pattern, characteristically blue because its warp threads are dyed with indigo while the weft threads are left white. This construction gives denim its distinctive look: deep blue on one side, paler on the reverse, and prone to attractive fading at points of wear. First produced in Europe, the fabric takes its name from the French phrase 'serge de Nîmes', meaning 'serge from Nîmes', a city in southern France associated with its early manufacture. Denim became globally famous through American workwear and, above all, blue jeans, which transformed it into one of the most widely worn textiles in the world. Today the word refers both to the material itself — as in a denim jacket or denim skirt — and, in the informal plural 'denims', to the garments made from it. Durable, versatile, and culturally iconic, denim is equally at home in fashion writing, everyday conversation, and descriptions of practical work clothing.

Etymology of denim
The word 'denim' derives from the French 'serge de Nîmes', meaning the twilled serge fabric originally associated with Nîmes, a city in southern France. The phrase was shortened and anglicized into a single English word, attested by the mid-19th century, as the fabric became central to American workwear. Its fame spread worldwide through blue jeans, cementing 'denim' as the standard term for this class of sturdy indigo-dyed cotton cloth.
How denim is actually used
In the singular, 'denim' functions as an uncountable mass noun referring to the cloth itself ('a bolt of denim'). In the plural, 'denims' informally denotes garments such as jeans. When used attributively before another noun, it acts adjectivally ('a denim skirt'), but this is standard noun modification rather than a distinct part of speech. The word carries casual, everyday connotations and is neutral to slightly informal in register.
