Answer:
definition by etymology
Explanation:
<em>Etymology</em> is called the study of the origin of individual words, their chronology, their integration into a language, as well as the source and details of their changes in form and meaning.
In languages with a long written history, etymology is a discipline related to philology and historical linguistics, which includes the study of the origin of words by investigating their original meaning, their structure, as well as their diachronic evolution, that is, possible changes that have occurred over time.
Also, to obtain some direct source, for example writing, by means of comparative linguistic methods, data related to extremely old languages can be reconstructed. Thus, through analysis of other related languages, linguists can make inferences about the language from which they originate and their vocabulary.
