“Goodbye,” as a single, closed word, is the correct and standard spelling.
The other variants — “good-bye,” “good bye,” and “goodby” — all exist in some form, but only one is standard in modern English.
This guide breaks down exactly which spelling to use and why.
What Does “Goodbye” Mean?
Goodbye is the universally accepted standard spelling in modern English dictionaries and style guides.
Example: “She waved goodbye as the train pulled away.”
Common uses of “goodbye” in everyday writing:
- “He said his final goodbye before boarding the flight.”
- “It’s hard to say goodbye to old friends.”
- “They exchanged a quick goodbye at the door.”
“Goodbye” in Different Writing Contexts
What Do “Good-bye,” “Good Bye,” and “Goodby” Mean?
These three forms carry the same meaning as goodbye, but none of them represent the current standard spelling.
Good-bye: A hyphenated variant that is largely considered old-fashioned or outdated.
Good bye: Spelled as two separate words, this is grammatically incorrect when used as a noun or an interjection meaning a farewell.
Goodby: An obsolete spelling variation that is rarely used today.

Memory Tip
The easiest way to remember the correct spelling:

Frequently Asked Questions
How to say goodbye in a classy way?
Elegant alternatives include “farewell,” “until we meet again,” or “take care.” These feel more polished than a simple “bye.”
Is Bye Bye flirty?
Not inherently — “bye bye” is typically playful or casual rather than flirty, though tone and context can shift its meaning.
How to write good bye correctly?
The correct, standard spelling is goodbye, written as one closed word — not “good bye” or “good-bye.”
Why do people say goodbye instead of bye?
Goodbye often feels more complete or formal than the shortened “bye,” making it common in situations that call for a slightly more deliberate farewell.
Why shouldn’t you say goodbye?
Some avoid “goodbye” in casual settings because it can feel overly final or formal; a lighter phrase like “see you soon” can feel warmer for short partings.
What is a rude way to say goodbye?
Abruptly saying “bye” and walking away without acknowledgment, or hanging up without warning, are often seen as rude ways to end an interaction.
What is the coolest way to say goodbye?
Casual, trendy options include “catch you later,” “peace out,” or “I’m out” — all popular, informal alternatives to a plain goodbye.
What’s a fancy word for goodbye?
Formal alternatives include “farewell,” “adieu,” and “au revoir” (borrowed from French).
How to say goodbye old fashioned?
Older, more traditional phrases include “until we meet again,” “God be with you” (the original root of goodbye), or the formal “good-bye,” hyphenated in vintage writing.
Conclusion
Goodbye is the only correct, standard spelling in modern English, while good-bye, good bye, and goodby all represent outdated or incorrect variants. Whether writing casually or formally, the single closed-word form is always the safest choice.
