What does desuetude mean?
Desuetude is a formal noun meaning the state of no longer being used, practiced, or observed — in short, disuse. When a custom, law, ritual, or institution gradually drops out of common practice without ever being formally abolished, it can be said to have fallen into desuetude. The word carries a slightly literary and often wistful connotation, evoking things quietly fading from memory rather than being deliberately discarded. It appears most often in elevated prose and in legal discussion, particularly within civil-law traditions where a statute may lapse into desuetude through long non-enforcement even though it remains on the books. Typical collocations include "fall into," "fall by way of," or "lapse into" desuetude. Borrowed into English in the early seventeenth century from French, and ultimately from Latin, desuetude remains a precise and elegant term for describing the quiet death of practices that once mattered.

Desuetude comes from the same Latin root as "sue" — it literally means what happens when something stops being "followed after."

Etymology of desuetude
Desuetude entered English in the early seventeenth century, borrowed from French désuétude, which derives from Latin dēsuētūdō, meaning "disuse." The Latin word combines the prefix dē- ("away from") with suēscere ("to become accustomed"), the same verb underlying "custom" and "accustomed." Cognates include French désuétude and Italian disuetudine.
How desuetude is actually used
Desuetude is a formal, somewhat literary word, more common in British English than American English. It is almost always used with abstract nouns such as laws, customs, traditions, and practices, and it frequently appears in legal contexts — notably in civil-law systems, where "desuetude" can denote the abrogation of a law through prolonged non-use.
