Is "Good Morning" One Word? I Found the Definitive Answer

My Quick Answer

After thoroughly researching English grammar rules, I can confirm the correct spelling is Good Morning (two words).

Goodmorning (one word) is definitely an incorrect spelling.

Why I Found It's Written as Two Words

When I started researching this question, I was surprised by how many people get this wrong. I discovered that the confusion often comes from comparing "good morning" with "goodnight." Let me explain what I learned.

The Basic Rule I Follow

Good morning is always written as two separate words. You're literally wishing someone a "good" (adjective) "morning" (noun). Since they're two distinct words with clear meanings, they remain separate.

Good Morning Spelling Rules - Two Words vs One Word

I found this pattern is consistent with other time-of-day greetings:

  • Good morning (two words) ✓
  • Good afternoon (two words) ✓
  • Good evening (two words) ✓
  • Good day (two words) ✓

The "Goodnight" Confusion: Why It's Different

This is where I found most people get confused. I noticed that "goodnight" is commonly written as one word, while "good morning" remains two words. Let me share what I discovered about why this happens.

ExpressionSpellingWhy I Found It's This Way
Good MorningTwo wordsUsed primarily as a greeting. Both words retain their individual meanings.
GoodnightOne wordOften used as a compound adjective (goodnight kiss) or noun (say goodnight). Has merged over time.
Good AfternoonTwo wordsUsed as a greeting. Follows the same pattern as good morning.
Good EveningTwo wordsUsed as a greeting. Follows the same pattern as good morning.

Important Note I Found

While "goodnight" is commonly one word, I did find that "good night" (two words) is also acceptable in some contexts, especially when emphasizing the "night" part. However, "goodmorning" as one word is never correct in standard English.

Memory Trick #1: The "Wishing" Method

When I say "good morning," I'm literally wishing someone a good morning. Since I'm using two distinct concepts (wishing good + the morning), I keep them separate in my mind and in writing.

Memory Trick #2: The Pattern Recognition

I noticed that all time-of-day greetings follow the same pattern:

  • Good + Morning = Two words

  • Good + Evening = Two words

The pattern is consistent! "Goodnight" is the only exception that became one word.

Frequently Asked Questions

Is "good morning" one word or two?

I found that "good morning" is always written as two separate words. "Goodmorning" as one word is incorrect in standard English.

Why is "goodnight" one word but "good morning" is two?

I discovered that "goodnight" has evolved into a single word because it's commonly used as a compound adjective or noun (like "goodnight kiss" or "say goodnight"). However, "good morning" is primarily used as a greeting and hasn't merged into one word.

Can I write "goodmorning" in informal texts?

While I understand you might see "goodmorning" in casual texts or social media, I still recommend using "good morning" (two words) even in informal situations. It's the correct spelling and shows better language skills.

What about "good afternoon" and "good evening"?

I found that both "good afternoon" and "good evening" are always written as two separate words, just like "good morning." The pattern is consistent for time-of-day greetings.

How can I remember that "good morning" is two words?

I use a simple memory trick: Think of it as "good" (wishing someone well) + "morning" (the time of day). Since you're wishing someone a good morning, keep them separate. The same applies to good afternoon and good evening.

Is "good bye" or "goodbye" correct?

I learned that "goodbye" is correctly written as one word. Unlike greetings (good morning, good afternoon), "goodbye" merged into a single word over time. This is an exception to the two-word pattern.

What's the correct way to use "good morning" in emails?

I recommend using "Good morning," (two words, with a comma) as an email greeting. For example: "Good morning, John," or "Good morning,". The two-word spelling is standard in all professional and personal email communications.
