A more thorough explanation:

ET

ET is a Latin conjunction that means "and". It was commonly used in Latin and Law French phrases.

• "Et cetera" - meaning "and so forth"
• "Et alii" - meaning "and others"
• "Et tu, Brute?" - meaning "And you, Brutus?"

These examples show how "et" was used to connect words or phrases together to indicate that there were more things to be included. For example, "et cetera" means "and so forth", indicating that there are more things that could be listed but are not necessary to mention. "Et alii" means "and others", indicating that there are more people or things that could be included in the list. "Et tu, Brute?" is a famous phrase from Shakespeare's play Julius Caesar, where it is used to express surprise and betrayal.
