To Fast

“To fast” should never be used. “To” is a preposition, which you cannot use whenever you want to modify an adjective like “fast.” It does not allow you to emphasize the meaning of the word.

  • Correct: I think it’s going too fast! If it doesn’t slow down soon, I’m pretty sure it’s going to cause a nasty accident.

  • Incorrect: He was driving to fast, which is why we decided to pull him over. It’s for his own good.

Too Fast

“Too fast” is the only correct form. It’s grammatically correct because it features an adverb (too) modifying an adjective (fast). Adverbs are designed to modify adjectives in this way. “Too” works by emphasizing the meaning of “fast.”

When using “too fast,” it means that something is going at an excessive speed. The speed is almost too much for someone or something to handle.

Why Do People Tend To Spell It Wrong?

Don’t worry if you’re spelling it wrong yourself. Even native speakers can mess it up sometimes because of how similar “to” and “too” sound when pronounced aloud. It’s common for people to mistake them because of what they hear when they are both said.

How To Remember If The Correct Spelling Is “To Fast” or “Too Fast”

Perhaps you’d benefit from a quick tip to help you remember the difference!

“Too” is correct when modifying an adjective. “Too” means “an excessive amount,” and saying “too fast” implies that something is moving far too quickly to handle. “Too” also contains an excessive amount of “O’s,” so you should always remember to spell it with two “O’s” rather than one.

Final Thoughts

You can only use “too fast” when you want to intensify the adjective. “Too” is an adverbial form, so it’s the only one that makes sense whenever you want to emphasize how “fast” something is. “To” is only a preposition, so it does not make sense to modify “fast.”
