Quick Answer

Form	Is It Correct?	Usage
Good morning	✅ Yes	The standard English greeting used in speech and writing.
Goodmorning	❌ No	A common spelling mistake in standard English.

If you’re wondering whether to write goodmorning or good morning, always choose good morning. Major dictionaries, including Merriam-Webster, Cambridge Dictionary, Oxford English Dictionary, and Collins Dictionary, recognize good morning as the correct spelling.

It is the preferred form in professional emails, business communication, academic writing, formal letters, and everyday conversation.

The Rule Explained

Good morning is an open compound, meaning it is made up of two separate words that work together as a greeting or salutation.

Unlike closed compounds such as goodbye, the expression good morning has remained two words in modern English. Standard dictionaries and English style guides continue to treat it as a phrase rather than a single word.

The first word, good, is an adjective expressing goodwill or politeness.

The second word, morning, is a noun referring to the early part of the day.

Together, they form one of the most common English greetings used in both spoken and written communication.

Examples:

Good morning, everyone!
Good morning, Professor Smith.
Good morning! I hope you’re having a wonderful day.

Because it functions as a greeting, the words stay separate in standard English spelling.

Why “Good Morning” Is Two Words

Many people wonder why good morning is written as two words while expressions like goodbye are written as one.

The answer lies in how English compound expressions evolve.

Some expressions gradually change from an open compound (two words) to a closed compound (one word). Others never make that transition because they continue to function as fixed greetings rather than independent vocabulary words.

For example:

Good morning ✅
Good afternoon ✅
Good evening ✅
Good night ✅

All of these remain two-word greetings in standard English.

By comparison:

Goodbye ✅

Originally written as good bye, it gradually became a closed compound through centuries of everyday use.

Today, good morning has not undergone that change. According to the Cambridge Dictionary and the Oxford English Dictionary, it remains the standard spelling in both British English and American English.

You may occasionally see goodmorning used in usernames, hashtags, brand names, domain names, or creative titles. However, these are stylistic choices rather than examples of standard English usage.

Memory Trick

Remember this simple rule:

If you’re greeting someone, write “good morning” as two words.

Think of the other daily greetings:

Good afternoon
Good evening
Good night

Since all of them are written as two separate words, good morning follows the same pattern.

Whenever you’re writing an email, letter, text message, presentation, or social media post, using good morning will ensure your English grammar, word spacing, and professional communication are correct.

What the Dictionaries and Style Guides Say

Leading dictionaries and writing authorities agree that good morning is the correct spelling in standard English.

Style Guide / Dictionary	Preferred Form	Notes
Merriam-Webster	Good morning	Listed as a greeting and salutation.
Cambridge Dictionary	Good morning	Used when greeting someone in the morning.
Oxford English Dictionary	Good morning	Recognized as a two-word expression.
Collins Dictionary	Good morning	Standard spelling in both speech and writing.

These references consistently treat good morning as an open compound rather than a single word. If you’re writing for school, work, publishing, or professional communication, following these standard references is the safest choice.

How Usage Has Changed Over Time

English is full of compound words that have changed over the centuries.

Some expressions begin as two separate words, later become hyphenated, and eventually turn into one word.

For example:

Web site → Website
Good bye → Goodbye
On line → Online

However, not every compound follows this pattern.

Greetings such as good morning, good afternoon, good evening, and good night have remained open compounds because they function as polite greetings rather than standalone vocabulary words.

Although you’ll occasionally find goodmorning in hashtags, usernames, product names, mobile apps, or website domains, these are branding or stylistic choices—not examples of standard English spelling.

Which Should You Use?

Your choice is simple.

If you’re writing emails, reports, essays, or professional documents → Use “good morning.”
If you’re texting friends or posting on social media → “Good morning” is still the correct spelling.
If you see “goodmorning” in a brand name, hashtag, username, or website → Treat it as a creative style, not a grammar rule.

Using good morning demonstrates accurate English spelling, proper word spacing, and professional writing skills.
