The guidelines above apply equally to "onto" and "on to." As a general observation, when "to" follows "on," it usually has its own role to play. Of note, the use of "into" and "in to" has nothing to do with UK or US writing conventions. If it doesn't, you're looking at the preposition "into." If it does have its own role, then keep "in" and "to" separate. If, for some reason, "to" follows "in" in your sentence, check that "to" has its own role to play (e.g., it's there to show an infinitive verb or to head a prepositional phrase).

(This one is correct because "to" marks the infinitive verb "to test." In other words, "to" has its own role to play in the sentence.) The prepositional phrase is "into the water.") (This is wrong because "to the water" is not the prepositional phrase. The prepositional phrase is "into the basket.") (This is wrong because "to the basket" is not the prepositional phrase. Confusion arises with verbs like "drive in," "dive in," "put in," and "fall in " because "drive into," "dive into," "put into," and "fall into" are also valid verbs.Įxample sentences with "into" and "in to": In the second one, "to" headed the prepositional phrase "to the police." That's quite a complicated concept if you're new to grammar, and, unfortunately, it's not the end of the story. In the first sentence, "to" marked "to see" as an infinitive.

So, in the two examples above, the word "to" was separated from "in" because "to" had its own role to play in each sentence. It is part of the prepositional phrase "to the police.") (In this example, the word "to" is a preposition in its own right.

(In this example, the verb is "hand in." It is called a phrasal verb because it is made up of two words. Paul wanted to hand the purse in to see if there was a reward.Here are some example sentences with "in to":
