Language change refers to the natural changes in a language over time as it is used by its speakers

In both natural languages and constructed languages, language change refers to the natural changes in a language over time as it is used by its speakers. Language change is also referred to as diachrony, and its study is called diachronic analysis.

In conlanging, language change can also be simulated, a process called diachronic conlanging or "doing diachronics". Use this tag for questions about the natural changes to a conlang, and the tag for the process of simulating change.
