When to us "TO" and "For"

Use TO in these cases:

1. Destination: “We’re going to Paris.”
2. What time it is: “It’s a quarter to 2.”
3. Distance: “It’s about ten miles from my house to the university.”
4. Comparing: “I prefer sleeping to working.”
5. Giving: “I gave the book to my sister.”
6. Motive/Reason – with verb:
7. “I came here to see you.”

Use FOR in these cases:

1. Benefits: “Yogurt is good for your digestion.”
2. Period of time: “We’ve lived here for 2 years.”
3. Schedule: “I made an appointment for May 3.”
4. Agree with: “Are you for or against the development of nuclear weapons?”
5. Doing something to help someone: “Could you carry these books for me?”
6. Motive/Reason – with noun: “Let’s go out for a drink.”
7. Function – with verb (-ing form): “A ladle is a big spoon used for serving soup.”

As you can see in #6, TO or FOR can be used for a motive/reason, but TO is always with a verb, and FOR is always with a noun. Here’s a good example:

• I came to New York to work.
• I came to New York for a new job.
