“To” and “for” are commonly used as prepositions. Changing a preposition, such as using “to” in the place of “for,” can completely alter the meaning of a sentence. Sometimes, if you use the wrong word, you’ll get a sentence that isn’t grammatically correct.So, let’s begin by talking about one of the most common (and most confusing) uses of “to” and “for”.
We usually use the prepositions “to” and “for” to talk about why somebody did something. Let’s look at some examples:
·Why did you travel to Cancun?
·I traveled to Cancun to visit my friends.
·Why did she buy a gift?
·She bought a gift for her brother’s birthday.
TIP: Use “to” when the reason or purpose is a verb. Use “for” when the reason or purpose is a noun.
USES OF TO:
1.- Use “to” when talking about movement or a change in direction
“To” is used as a preposition if there’s movement, a transfer or a change in direction from one point to another.
For example: I need you to take these books to Mary.
2.- Use “to” with infinitive verbs
Any English verb in the infinitive form will include the word “to.” You will frequently see this construction in English sentences.
For example: Nina loves to talk on the phone.
USES OF FOR
1.- Use “for” when expressing thanks or gratitude
If you want to thank someone, you’ll usually use the word “for” to explain why you’re thanking them.
The word “for” will be followed by a noun or gerund (a verb that ends with “-ing”).
For example: Thank you for teaching me to play the guitar.
2.- Use “for” when talking about a duration of time
“For” is also used to talk about a length of time during which something happened.
For example: I waited at the station for two hours.
3.- Use “for” when expressing support and agreement
“For” is used to indicate agreement with or support of a cause.
For example: Are you for or against the women’s movement?
