Goodbye or good bye? The correct spelling is goodbye, written as one word with no space and no hyphen. “Good bye” as two words is a common spelling mistake. This guide explains the difference, the usage, and clear examples.
What Does Goodbye Mean?
Goodbye is a parting word we use when we leave someone. It works as a noun (“a tearful goodbye”) and as an interjection (“Goodbye!”). Merriam-Webster defines it as a closing remark or gesture at parting.
It is a closed compound word, so the two parts have fused into one. The word dates back to 1575 and began as a shortened form of “God be with you.”
Goodbye Examples in a Sentence
Here are simple ways to use goodbye in a sentence:
- She waved goodbye as the train pulled away.
- It’s hard to say goodbye to old friends.
- We hugged and said our goodbyes at the door.
- He typed a quick goodbye before logging off.
| Context | Example |
|---|---|
| Everyday speech | “Goodbye! See you next week.” |
| Formal writing | The letter closed with a warm goodbye. |
| Emotional moments | Saying goodbye to her childhood home was hard. |
| Digital messages | A short goodbye note appeared in the chat. |

What Does Good Bye Mean?
Good bye carries the same meaning as goodbye. It is a farewell. The problem is the spelling, because the two-word form is not standard.
Most people see “good bye” as a typo. It shows up mostly in fast texts and casual messages. Standard dictionaries list the one-word form as the main entry.
Good-bye vs Good Bye: Old Style vs Mistake
Good-bye (with a hyphen) is an older variant. Merriam-Webster still lists it, along with the rarer “good-by” and “goodby.” Still, the AP Stylebook prefers goodbye.
So the hyphenated form is dated, while the two-word form is simply wrong. Here is how the forms compare:
| Form | Status | Where You’ll See It |
|---|---|---|
| Goodbye | Standard | Books, emails, news, school writing |
| Good-bye | Older variant | Vintage books, old letters |
| Good-by / Goodby | Rare variant | Historical or older texts |
| Good bye | Incorrect | Quick texts, typos |

Goodbye vs Good Bye Differences Chart
The main difference between goodbye and good bye is spelling. One is accepted in dictionaries, and the other is a common error. Both express the same farewell.
| Feature | Goodbye | Good Bye |
|---|---|---|
| Spelling | One word | Two words |
| Correct? | Yes | No |
| Best use | All writing, formal and casual | Avoid it |
| Example | “She said goodbye.” | “She said good bye.” (incorrect) |
Both forms once competed in print. Grammarphobia notes that “God be with you” and the shortened version lived side by side until the early 1800s. Google Books Ngram data suggests the one-word spelling pulled ahead of the hyphenated one around 1960.
