Summary of To and Too

Verbs are doing words like to dance, to sit, to fly, to think. (See lesson Verbs.)

When to is in front of a verb, the verb is said to be in its infinitive form.
  • She likes to dance. (< verb to dance in its infinitive form)
  • She dances. (< verb to dance not in its infinitive form)

As explained above, the infinitive form of a verb comprises of to and the verb itself (e.g., to laugh). It is a good idea to avoid putting any words between them. This is called a split infinitive, which lots of your readers will probably consider an error. (More on that below.)
  • Our mission: to boldly go where no man has gone before.
  • (The word boldly should not appear between to and go.)
  • You have to really mean it.    
  • (The word really should not appear between to and mean.)
If rewording your sentence to avoid a split infinitive makes it sound too contrived, then just use the split infinitive. The split infinitive is not really an error at all. However, it is worth avoiding because there's a fair chance that lots of readers will think it is.)
