goodbye
UK: ɡʊdˈbaɪ | US: ɡʊdˈbaɪ
n. an expression used when parting; a farewell
interj. used to express good wishes when parting or ending a conversation
The word "goodbye" originated as a contraction of the phrase "God be with ye" (or "you") in Middle English. Over time, "God" morphed into "good" due to phonetic shifts and folk etymology, while "be with ye" was shortened to "bye." The modern form "goodbye" emerged in the 16th century as a polite farewell, blending the well-wishing "good" with the abbreviated "bye." This reflects the cultural tendency to soften religious expressions into secular ones while retaining their original intent of blessing.
