goodbye

This term functions as both a social ritual and a concrete event. As an interjection, it serves as a standard closing to an interaction, ranging from casual to formal. It carries a sense of finality or temporary separation, often evoking emotions of sadness or anticipation depending on the duration of the parting. When used as a noun, it refers to the specific utterance or gesture of departure. While typically countable in the sense of "a goodbye," it is frequently used in the plural "goodbyes" to describe the prolonged process of saying farewell to multiple people or a lingering departure.
