The phrases too fast and to fast are often confused because to and too sound exactly alike. Since they’re homophones, it’s easy to type the wrong word without noticing. However, only too fast is correct when you mean excessively fast or faster than desired.
The phrase to fast is not usually correct before the adjective fast. It only appears when to is part of an infinitive (such as to fast, meaning “to abstain from food”). Understanding the different roles of to and too will help you avoid one of the most common spelling mistakes in English.
