"Adiós" is a Spanish word that means "goodbye." It is commonly used when parting from someone, whether temporarily or permanently. The term is derived from the phrase "a Dios," which translates to "to God," reflecting a wish for divine protection upon leaving. In many Spanish-speaking cultures, saying "adiós" can carry emotional weight, especially in farewells. It is often accompanied by gestures like hugs or handshakes. Other variations include "hasta luego" (see you later) and "hasta pronto" (see you soon), which convey different levels of permanence in the goodbye.
