English as a Second Language/Comma before "too" at the end of sentence


This is really confusing me. There are many occasions where writers added comma before "too" at the end of the sentences. On the other hand, some writers omit the comma!! Which one is correct grammatically? For example,

1) I like apples, too.


2) I like apples too.

Which one is correct?

Moreover, is this sentence correct?

I, too, like apples.

Or this is correct?

I too, like apples.

Hello Den,

interesting question you have.

You can write the sentences either way. It’s entirely up to you.

Most of the time I don't have to use a comma with “too” because these sentences don't need a pause. So I would say:

I like apples too.
I too like apples.

If for some reason you want to emphasize an abrupt change of thought, then you can use commas to indicate pauses:

I like apples, too.
I, too, like apples.

There really is no right or wrong here in my opinion.

I hope this helps.

Looking forward to more of your interesting questions.
