What is the difference between want to and to?

"Want to" is a modal verb phrase used to express desire or intention. It is made up of two words: the verb "want" and the infinitive "to." "To" is an infinitive marker that is used before the base form of a verb. It can also be used in other constructions, such as noun phrases, adjective phrases, and adverb phrases.

Here are some examples of how "want to" and "to" are used in sentences:

- I want to go to the beach. (In this sentence, "want to" is used to express the speaker's desire to go to the beach.)

- I need to buy groceries. (In this sentence, "to" is used as an infinitive marker before the verb "buy.")

- The book to read is on the table. (In this sentence, "to read" is an adjective phrase that modifies the noun "book.")

- We walked down to the park. (In this sentence, "to" is used in an adverb phrase that indicates the direction in which the speaker and their companions walked.)
