When you’re congratulating someone directly, the correct word is “congratulations,” always plural. According to Merriam-Webster, the singular form “congratulation” exists, but it’s used almost exclusively in formal phrases like “a letter of congratulation,” not as a standalone exclamation.
Why “Congratulations” Is Always Plural
“Congratulations” behaves like a small group of English nouns that appear mainly in plural form even when referring to a single event, similar to “thanks,” “regards,” or “condolences.” When you say “Congratulations!” you’re technically expressing multiple feelings of praise, joy, or acknowledgment at once, not just one, which is why the “s” stays even for a single occasion.
When “Congratulation” (Singular) Is Correct
There is a legitimate singular use, mainly in formal or descriptive writing:
“He sent a letter of congratulation.”
“She received many messages of congratulation and support.”
Outside of set phrases like these, the singular form sounds noticeably off to most native speakers.
Congratulations vs. Congratulatory
“Congratulations” is a noun and interjection. If you need an adjective to describe something related to congratulating, such as a card or a note, English typically uses “congratulatory” instead:
- ✅ “She wrote a congratulatory note.”
- ⚠️ “She wrote a congratulation note.” (unusual)
- ✅ “Congratulations on your promotion!”
Examples in Context
- ✅ “Congratulations on your new job!”
- ❌ “Congratulation on your new job!”
- ✅ “Please accept my congratulations.”
- ✅ “He offered his congratulation to the winner.” (formal, rare)
