Many learners often feel confused about when to use “to fast” and “too fast.” This is something I’ve seen repeatedly in classroom settings and in emails from students. As a tutor, I always remind them to slow down and think about the sentence they’re writing. For example, “to fast” is about planning not to eat, usually for health or religious reasons.
“Too fast,” on the other hand, means something is happening quicker than expected. One of my students once wrote, “Give me in English not cordings”—a simple request, but it shows how easy it is to get the phrases wrong if you’re not paying attention. (Exactly 144 characters)
In my experience, the best way to build confidence is by learning from real examples and improving your understanding over time. I tell my students—even native speakers make mistakes. It’s common. The goal is to be clear in your message, whether you’re writing to a friend or in a professional setting.
Strong grammar starts with knowing the difference between similar words and having the insight to decide which one fits best in your writing.
Understanding the Real Difference Between “To” and “Too”
Let’s clear the air. These two little words sound identical, but their meanings—and their grammar functions—are completely different.
Here’s a simple breakdown:
| Word | Part of Speech | Meaning | Example |
| To | Preposition / infinitive marker | Indicates direction, recipient, or purpose | I went to the store.She wants to learn. |
| Too | Adverb | Means “also” or “excessively” | That’s too much!I’m coming too. |
So, when you’re describing how fast something is, the correct word is always “too”—because you’re using an adverb to modify another word, like “fast.”
Why “Too Fast” Is the Correct Phrase
When you say something or someone is “too fast,” you’re using “too” as an adverb. It means more than is needed, expected, or acceptable.
Examples:
- He was driving too fast to stop in time.
- This lecture is going too fast for me to take notes.
- You’re speaking too fast—slow down!
In each case, “too” modifies the adjective “fast”, showing that the speed is excessive.
So remember: If you’re describing an excessive speed, “too fast” is the right phrase.
Why “To Fast” Is Always Wrong (In Most Cases)
Now let’s talk about the common mistake: “to fast.”
It might look okay, but it doesn’t follow standard English grammar rules—unless you’re using the rare verb “to fast,” meaning to abstain from food.
Let’s explain:
| Phrase | Correct? | Explanation |
| “To fast” | ❌ | There’s no verb following “to,” and “fast” isn’t a verb in this context. |
| “Too fast” | ✅ | “Too” is an adverb describing the adjective “fast.” |
Correct: She talks too fast.
Incorrect: She talks to fast.
How “Too” Works in Sentences (With Real Examples)
You’ll see “too” doing a few key jobs in English. Here’s how it works in different situations:
Before Adjectives
- It’s too cold to go outside.
- That movie was too long.
Before Adverbs
- She runs too quickly to catch.
- He works too slowly.
Before Much/Many
- I have too much work this week.
- There were too many people in the room.
To Show Agreement
- I’m hungry.
— I am too!
Quick Tip: If you can replace the word with “also” or “very,” you’re probably looking for “too.”
When “To” Is Actually Correct
There are many correct uses of “to” in English. It’s a preposition or an infinitive marker. Here’s how it’s used:
As a Preposition
- I’m going to the store.
- Give it to your teacher.
With Infinitive Verbs
- I want to read more.
- He needs to study.
But NEVER use “to” before an adjective like “fast”—that’s the job of “too.”
“Too Fast” vs. “To Fast” in Context
Let’s look at these side-by-side examples:
| Sentence | Correct? | Why? |
| He’s driving too fast. | ✅ | “Too” modifies “fast” (adverb + adjective). |
| He’s driving to fast. | ❌ | “To” needs a verb or noun, not an adjective. |
| I’m going to fast during Ramadan. | ✅/Rare | Only correct if “fast” is a verb meaning “to abstain from food.” |
So yes—“to fast” is grammatically correct only when “fast” is a verb, like during religious fasting. But in everyday use, “too fast” is almost always what you mean.
How to Never Confuse “To” and “Too” Again
Here are a few tricks that work:
Memory Mnemonics
- Too = extra “o” for “extra”
If it means “excessively” or “also,” use too. - To = direction or purpose
Use “to” when talking about a place, purpose, or verb.
Sound Clues
They sound the same, so you must rely on sentence structure to choose the correct one.
