When words share the same etymology and meaning they are called?

Words that share the same etymology and meaning are called cognates.

Here's a breakdown:

* Etymology: The study of the origin and historical development of words.

* Cognates: Words that have a common ancestor and share a similar meaning.

For example, the English word "father" and the Spanish word "padre" are cognates. They both come from the Proto-Indo-European word *pater, meaning "father".
