Day 256: Place a comma before a final too that means also.

The word too has two meanings: excessive and also. When too is used to mean also, and when it is written at the end of a sentence, put a comma before it. Consider these statements by John.

“I want to go to the store, too.”

“I want to go to this store and that store, too.”

“I will buy bananas and grapes, too.”

Be careful when using too in this way. The meaning might not be clear without the context. For example, the first sentence might mean that Sally wants to go to the store and that John also wants to go to the store. It also might mean that John wants to go to several places but also wants to go to the store. You have to write these sentences carefully to ensure that the meaning is clear.

To further explain how this is tricky, consider the third sample. Perhaps Sally said that she will buy bananas and grapes. John replies that he will also buy bananas and grapes. Perhaps John means that he will buy bananas and that he will also buy grapes. You will need to provide the context.

When both options are in the sentence (e.g., “this store and that store”), we try to revise sentences so they don’t need too, thus removing an unnecessary word and avoiding this confusion.

In either case, the comma goes before the final too.
