Many English verbs can take two objects at once: one that directly receives the action, and one that receives the direct object itself. Knowing which is which decides word order and whether a preposition like to or for is needed.

A direct object answers the question "what?" or "whom?" after the verb. An indirect object answers "to whom?" or "for whom?" and tells you who benefits from or receives the direct object.
Here, the book is the direct object (what she gave), and him is the indirect object (who received it).
This is the rule that decides whether a sentence needs a preposition at all, and it depends entirely on the order the two objects appear in. When the indirect object comes before the direct object, no preposition is needed. When the indirect object comes after the direct object, it needs to or for in front of it.
Only certain verbs, called ditransitive verbs, can take both a direct and an indirect object. The most common ones fall into a few clear groups:
Verbs like give, hand, offer, and lend.
Verbs like send, mail, and bring.
Verbs like tell, show, and teach.
Verbs like make, buy, and cook.
You can easily test for each object by asking two targeted questions after the verb:
| Question | Finds |
|---|---|
| Subject + verb + what / whom? | Direct object |
| Subject + verb + direct object + to / for whom? | Indirect object |
Practice spotting both objects in different sentence patterns:
| Sentence | Direct Object | Indirect Object |
|---|---|---|
| She gave him the book. | the book | him |
| He sent her a message. | a message | her |
| They told us the news. | the news | us |
| She bought a gift for her mother. | a gift | her mother |
Watch out for preposition placement and exception verbs that never drop their prepositions:
| Incorrect | Correct |
|---|---|
| She gave to him the book. | She gave him the book. / She gave the book to him. |
| He explained me the problem. | He explained the problem to me. |
| She bought for him a gift. | She bought him a gift. / She bought a gift for him. |
Learna AI listens for the object word order in a sentence and checks whether a preposition is needed based on whether the indirect object comes before or after the direct object. It also flags verbs like explain and suggest that always require to or for, regardless of word order, since these exceptions catch out even advanced learners. Learners practicing ditransitive verbs with Learna report a 69% improvement in choosing the correct word order and preposition.
Once direct and indirect objects feel steady, the broader rules behind object placement connect naturally to syntax and word order, which covers sentence-level word placement more generally.
Put your grammar knowledge into practice with Learna's learning paths:
The noun or pronoun that directly receives the action of the verb, answering the question "what?" or "whom?" after the verb.
The noun or pronoun that receives the direct object, answering "to whom?" or "for whom?" the action was done.
Ask "verb + what?" or "verb + whom?" after the subject and verb. In "She gave him the book," gave what? the book.
Ask "to/for whom?" after identifying the direct object. In "She gave him the book," gave to whom? him.
When the indirect object comes after the direct object: She gave the book to him, or She bought a gift for him.
Verbs that can take both a direct and an indirect object, such as give, send, tell, show, buy, and make.
No, only ditransitive verbs can. Verbs like eat or sleep only take a direct object, or no object at all.
Adding to or for even when the indirect object comes directly after the verb, as in "She gave to him the book," which should drop the preposition.
No, verbs like explain, describe, and suggest always keep to, even when the indirect object comes right after the verb: He explained the problem to me.
No, an indirect object only exists because it receives the direct object, so the two always appear together in the same sentence.
An indirect object can appear without a preposition when it comes before the direct object; once a preposition like to or for is added, it functions as a prepositional phrase instead.
Object pronouns like him, her, them, and us can serve as either direct or indirect objects, following the same word order rules as full nouns.
Learna AI checks the word order of a sentence with two objects and flags whether a preposition is missing or unnecessary based on that order.
Yes. Learna AI tracks which verbs always require to or for and corrects a learner who drops the preposition after these specific verbs.
