The Meaning of To

“To”, spelled with one “o”, is a preposition used in English in a variety of ways. 

A common use of “to” is before a verb’s infinitive form, such as “to drive”, “to eat” or “to go”.  

When using “to” to form the infinitive, follow the pattern: to + base verb.

Another use is for direction (movement); for example, “I am going to Spain next week.” 

A third possible use is as a preposition of possession, such as “The book belongs to the library.”

Examples:

• Gwen is biking to school.
• Frankie wants to learn how to code at university.
• The laptop belongs to the company.

The Meaning of Too

The word “too” is an adverb used to describe excess, an addition, or a response to a previous statement. 

For example, if you made more soup than you can eat, then you might say, “I made too much soup.” This use of “too” indicated excess.

If you wish to use “too” in a response to a previous statement, the exchange might go like this:

• “It was nice to meet you.”
• “It was nice to meet you, too.”

In this exchange, “too” could be used interchangeably with “as well”. When using “too” to refer to something additional, usually (but not always) the word can be replaced with “as well” or “also.”

Examples:

• I wanted to go for a walk, but it was too cold outside.
• I brought my rollerblades and my bike, too.
• They have to think about the weather, too, when planning a camping trip.

Definition of Two

“Two” is the written representation of the number 2. It can be used as an adjective (two carrots), a pronoun (How many items were left? There were just two.), or a noun (count by twos). 

Examples:

• The train will arrive on platform two.
• There were several items for sale, I bought two.
• When they asked how many tickets to buy, I said two.

When to Use To vs. Too vs. Two: Examples

It is easiest to remember when to use “two,” because it is the spelling of the number 2. If the word could be replaced with “2”, then use the spelling “two”.

The words “to” and “too” can be more difficult to differentiate. One helpful trick is to think about whether the word means extra or excess. If something is extra (“I want to come, too!”) or in excess (“That’s too much ketchup”). 

Practice Examples:

• I asked Ana to present at the staff meeting to.
  
  • Check for meaning: The first “to” in this sentence is paired with a verb to make an infinitive (to present). The second “to” could be replaced with “as well”.
  • Correct as: I asked Ana to present at the staff meeting too. 
• Shannon wanted too go two the park.
  
  • Check for meaning: The first “too” in this sentence is paired with a verb to make an infinitive (to go). The second “two” is acting as a preposition of movement.
  • Correct as: Shannon wanted to go to the park.
• A table for too, please.
  
  • Check for meaning: This sentence is using “too” as a noun, referring to two people. 
  • Correct as: A table for two, please.

Additional Examples of To vs Too vs Two:

• They came to the meeting.
• She brought us each two sandwiches, but I was too full to eat.
• He had to complete two assignments for the course.
• We wanted to go camping for two weeks, but it rained too much to stay.
