Quick answer: The correct form is always good morning (two words). “Goodmorning” is a common typo and is never correct in standard English, whether you are writing a formal email or a casual text message.
You might see “goodmorning” typed quickly in chat apps or social media comments, but it is technically incorrect. This confusion usually stems from the speed of digital communication, where spaces are often skipped accidentally. However, in any context that requires proper grammar—such as professional emails, academic papers, or published content—you must use the two-word separation.
| Term | Meaning / When to use | Example sentence |
|---|---|---|
| good morning | The standard, correct greeting used before noon. | “Good morning, everyone. Let’s begin the meeting.” |
| goodmorning | An incorrect spelling; a typo that merges two words. | (Incorrect) “I sent him a goodmorning text.” |
When to use good morning
Use good morning whenever you are greeting someone during the early part of the day, typically from waking up until 12:00 PM (noon). It functions as both an interjection (a standalone greeting) and a noun phrase (referring to the time of day).
As an editor, I see this greeting used in three primary contexts, and the two-word rule applies strictly to all of them:
- Direct Address: When speaking or writing directly to someone.
- Example: “Good morning, Sarah. Did you get the report?”
- Descriptive Noun: When referring to the quality or atmosphere of the morning.
- Example: “We enjoyed a good morning hike before the rain started.”
- Compound Modifiers: When used as an adjective before a noun, it is often hyphenated as good-morning, but still never merged into one word.
- Example: “She gave him a good-morning kiss before leaving for work.”
The space between “good” and “morning” is non-negotiable in standard English. “Good” is an adjective modifying the noun “morning.” In English grammar, adjectives and nouns remain separate words unless they have evolved into a specific closed compound over centuries (like “bedroom” or “sunflower”). “Good morning” has not undergone this linguistic merger.
Consider this real-world example from a corporate email I recently proofread:
- Incorrect: “Goodmorning team, please review the attached slides.”
- Correct: “Good morning, team. Please review the attached slides.”
The error in the first sentence distracts the reader immediately. It signals carelessness, which can undermine the professional tone of the rest of the message. Always insert that space.
When to use goodmorning
The short answer is: never.
There is no scenario in standard American or British English where “goodmorning” is the accepted spelling. It is not an alternative variant, it is not a regional dialect preference, and it is not an archaic form. It is simply a mistake.
However, understanding why people make this mistake can help you avoid it. The error usually occurs in two specific digital environments:
- Fast-Paced Messaging: In SMS, WhatsApp, or Slack, users often type quickly without autocorrect checking proper spacing for common phrases. If you type “goodmorning” quickly, your phone might not flag it because it sees two valid root words, even if the spacing is wrong.
- Hashtags and Usernames: On social media platforms like Instagram or Twitter, spaces are not allowed in hashtags. Therefore, you will see #goodmorning. This is a technical constraint of the platform, not a grammatical rule. Do not let social media formatting influence your standard writing.
Here is a realistic example from a resume summary that I corrected for a client:
- Incorrect: “Energetic professional with a goodmorning attitude and strong work ethic.”
- Correct: “Energetic professional with a positive morning attitude and strong work ethic.”
In this case, the candidate was trying to use “good morning” as an adjective, which is awkward even when spelled correctly. But the merged spelling made it look like a completely unfamiliar term. By separating the words—or better yet, rephrasing for clarity—the sentence becomes professional and readable.
Another common place I see this error is in automated system messages. If you are coding a bot or writing copy for an app notification, ensure your string variables include the space.
- Incorrect Code Output: “Goodmorning! Your order has shipped.”
- Correct Code Output: “Good morning! Your order has shipped.”
While it seems minor, these micro-copy errors accumulate. They make a brand feel less polished. Always enforce the two-word structure in your style guides.
How to remember the difference
If you find yourself second-guessing whether to merge the words, use this simple mental check: The “Good Night” Test.
No one writes “goodnight” as a single word in formal writing either (though “goodnight” is slightly more accepted in informal contexts than “goodmorning,” it is still technically two words: “good night”). Think about the phrase “good afternoon.” You would never write “goodafternoon.” You would never write “goodevening.”
The pattern is consistent: Good + [Time of Day] = Two Words.
- Good morning
- Good afternoon
- Good evening
- Good night
Another effective mnemonic is to visualize the physical action of the greeting. When you say “good morning,” you pause slightly between the words. That pause is the space. If you slur them together into “goodmorning,” you sound rushed or unnatural. Let your typing mimic your speech: distinct words, distinct spaces.
For editors and writers who deal with high volumes of text, I recommend using a “Find and Replace” trick in your word processor. Search for “goodmorning” (one word) in your document. If you get any hits, you know you have an error to fix. This is faster than reading every line manually and ensures 100% accuracy.
Common mistakes and exceptions
While the rule is straightforward, there are edge cases and related errors that often trip up writers.
The Hyphenated Exception
As mentioned earlier, when “good morning” is used as a compound adjective before a noun, it takes a hyphen. This is a standard English rule for compound modifiers.
- Correct: “He waved a good-morning hello from across the street.”
- Incorrect: “He waved a good morning hello from across the street.” (Ambiguous)
- Incorrect: “He waved a goodmorning hello from across the street.” (Wrong)
Note that even in this hyphenated form, the words are not merged. The hyphen replaces the space, but the letters remain distinct. Never use “goodmorning” here.
US vs. UK Differences
There is no difference between American English and British English regarding this phrase. Both varieties require the space. You will not find “goodmorning” in The Oxford English Dictionary or Merriam-Webster as a standard entry. It is universally considered an error in both regions.
However, cultural usage varies. In the UK, “Morning!” (dropping the “good”) is a very common casual greeting. In the US, “Good morning” is retained more often even in semi-casual settings. But in both cases, if you include the word “good,” it must be separated from “morning.”
Capitalization Rules
A frequent follow-up question is about capitalization. Should it be “Good Morning” or “good morning”?
- Start of a sentence: Capitalize the first letter. “Good morning, everyone.”
- Mid-sentence: Keep it lowercase unless it’s part of a title. “I said good morning to her.”
- Titles/Headlines: Follow title case rules. “Good Morning Sunshine: A Review.”
Do not capitalize both words in the middle of a sentence just for emphasis. That is a stylistic choice seen in marketing copy (“Have a GOOD MORNING!”), but it is not standard grammar. Stick to sentence case for normal prose.
Autocorrect Failures
Modern smartphones are smart, but they are not perfect. Some older keyboard dictionaries may not flag “goodmorning” as an error because it contains valid substrings. Do not rely solely on the red underline. If you are writing important content, always double-check common greetings manually.
the phrase “good morning” has deep historical roots in English greetings, evolving from longer forms like “God give you a good morrow.” <sup>1</sup> This historical separation reinforces the modern grammatical requirement for two distinct words. The evolution of language tends to merge words over centuries (like “to day” becoming “today”), but “good morning” has resisted this merger, likely because it is used so frequently as a distinct polite formula rather than a single conceptual unit.
Frequently Asked Questions
Is “goodmorning” ever correct in informal texting? While commonly seen in texts due to speed, it is still technically a typo. In casual chats with friends, it may be understood, but it is not “correct” English. If you want to be precise, use the space.
Should I capitalize “Good Morning” in an email subject line? Yes, in email subject lines, it is standard to use title case or sentence case. “Good Morning: Meeting Update” or “Good morning: Meeting update” are both acceptable. Avoid “goodmorning.”
What is the difference between “good morning” and “top of the morning”? “Good morning” is the standard global greeting. “Top of the morning” is an idiomatic, often stereotypical Irish greeting. Both use separate words. Neither is merged.
Can I use “GM” instead of “good morning”? “GM” is a common abbreviation in digital slang, particularly in crypto and tech communities. It is acceptable in those specific informal contexts but should never be used in formal writing. Even then, it is an abbreviation for the two-word phrase, not a replacement for the spelling rule.
The cultural impact of the phrase is significant, appearing in countless songs and media titles. For instance, The Beatles’ song “Good Morning Good Morning” uses the standard two-word format repeatedly, reinforcing the correct usage in popular culture. <sup>2</sup> When in doubt, remember that if The Beatles and your high school English teacher agree on the spacing, you should too.
