What Does “Millions of Dollar” Mean?

Let’s be honest first: “millions of dollar” is NOT correct in standard English.

Simple Definition

“Millions of dollar” tries to mean a very large amount of money, but the grammar is wrong.

When Do Learners Use It?

Many learners use this phrase by mistake when they:

• Forget to make nouns plural
• Translate directly from their native language
• Think “million” already shows plural, so “dollar” stays singular

Grammar Rule

In English, when you say “millions of”, the noun after must be plural.

So:
❌ millions of dollar (incorrect)
✅ millions of dollars (correct)

Example Sentences (Incorrect Usage)

These are common mistakes learners make:

All of these sentences are wrong because “dollar” is singular.

Common Learner Confusion

• “Million” already shows many, so “dollar” doesn’t need “s”

But English grammar works differently.

Think like this:

• “Millions of” = many millions
• So the noun must also be plural
