How do you say "Hello, everyone" in Latin?

The phrase "Hello, everyone" in Latin is accurately expressed as "Salvete, omnes." In Latin, "salvete" is the plural form of the greeting, which means "hello" or "greetings" and is used when addressing more than one person. "Omnes" translates to "everyone," making this phrase a suitable and friendly salutation for a group.

The use of "salvete" signifies the plural form, intended for addressing multiple people, which aligns with the context of greeting a group as opposed to an individual. This distinction is crucial as Latin differentiates between singular and plural forms in both verb usage and personal pronouns, so choosing the correct form enhances clarity and appropriateness in communication.

The other options either use incorrect forms or suggest singular greetings, which do not fit the intent of addressing a group. Thus, "Salvete, omnes" stands out as the correct and appropriate greeting for the intended meaning.
