I Too or I, Too? (Comma Rules)

“I, too” with a comma is more correct than “I too” because it indicates that the word “too” modifies the whole sentence. Furthermore, you need to put a second comma. E.g., “I, too, have been to New York.” However, “I too” without commas is acceptable in informal texts and messaging.

If you are writing a standard text or you want the grammar to be correct in your writing, you should include a comma with “I, too.”

In this example, the word “too” is enclosed in commas, which modifies the whole sentence:

  • Correct: I, too, need to speak with Hannah today.

However, in this example, “too” is not enclosed in commas, so it only modifies the word  “I” and “need.” Therefore, grammatically speaking, this example is incorrect:

  • Incorrect: I too need to speak with Hannah today.

However, in informal messaging, people often omit the commas entirely.

Also, the following example is incorrect because if you add the comma before “too,” you must add one afterward:

  • Incorrect: I, too need to speak with Hannah today.

Finally, the terms “I, too” and “me, too” often cause a lot of confusion. You should use ”me too” if you are the object of the sentence.

  • I was given a very nice birthday present.
  • Me, too.

Whereas if you are the subject of the sentence, you should use “I, too.”

  • I am going to the beach.
  • I, too (am going to the beach.)

However, even though this is the rule, it is common that people use “me, too” as a universal response when they are both the subject and object. Furthermore, you should always use a comma after the pronoun in both versions.

Read on to discover more about how to correctly use commas with “I, too.”

I, Too

You can use the term “I, too,” to indicate you want or feel the same as someone else.

However, to be grammatically correct, you should always put a comma before and after the “too” when using “I, too” in a sentence.

  • A – I am hungry.
  • B – I, too, would like something to eat.
  • A – I studied computer science at college.
  • B – I, too, studied computer science.

Furthermore, using the word “too” enclosed in commas is the same as placing it at the end of the sentence. When you place commas around “too” like this, it modifies the whole sentence.

  • A – I am going to Hawaii for the Christmas vacation.
  • B – I, too, am going to Hawaii for the Christmas vacation.

The last sentence could be rephrased as:

  • B – I am going to Hawaii for the Christmas vacation, too.

I Too

The term “I too”, without commas, is grammatically incorrect. However, it is common in informal messaging that people omit commas.

  • A – I passed the exam!
  • B – Incorrect: I too passed the exam!

So, while you may see the above version frequently, the correct version would have commas.

  • B – Correct: I, too, passed the exam!
