Désuète

Désuète is a French adjective meaning obsolete, outmoded, or no longer in fashion or use. It is typically applied to things that have fallen into disuse, such as outdated technology, old-fashioned customs, or words that are no longer commonly spoken. The term can also describe a person whose style or opinions are considered old-fashioned.

The concept of désuétude is not limited to language. It can be observed in many aspects of life. For example, a piece of technology that was once cutting-edge may become désuète as newer, more advanced versions emerge. Similarly, social customs or fashions that were once popular can become désuète over time. The word itself is a cognate of the English word "desuetude," which carries a similar meaning of disuse or discontinuance.

While désuète implies a lack of current relevance, it does not necessarily mean something is worthless. Many désuète items or practices can still hold historical, cultural, or sentimental value. For instance, antique objects are often considered désuète in terms of their practical function but are highly prized for their age and craftsmanship. Similarly, some older words, though no longer in common parlance, might be preserved in literature or academic study. The perception of something as désuète is often subjective and dependent on societal trends and technological advancements.
