Nouns:
* Valet: This word, meaning "attendant," is derived from the accusative form of "vale," which can mean "farewell." It was originally used to refer to a servant who saw someone off, hence the connotation of "attending" or "assisting."
* Valedictory: This adjective, meaning "pertaining to a farewell," is derived from the noun "valedictoria," which is a Latin phrase meaning "farewell speech." It is often used to describe a speech given at a graduation ceremony or other farewell occasion.
Verbs:
* Valere: This verb, meaning "to be strong, to be well," is the root of "vale." It is the source of many English words, including "valid," "value," "valorous," and "valiant."
* Valeo: This is a more archaic form of "valere," meaning "to be strong, to be healthy." It is not as commonly used in modern English, but its influence can be seen in words like "invalid," "valor," and "valedictory."
Other:
* Vale: This word itself, meaning "farewell," can be used as a standalone greeting or as part of a phrase like "vale, vale!" or "vale, et bene vale!" which both mean "farewell, and farewell well!"
