When to use she or her in a sentence?

Here's a breakdown of when to use "she" and "her" in a sentence:

"She" is a subject pronoun. It is used when the noun or pronoun is performing the action in the sentence.

* Examples:

* She went to the store. (She is the one performing the action of going)

* She is a talented artist. (She is the subject of the sentence)

"Her" is an object pronoun. It is used when the noun or pronoun is receiving the action in the sentence.

* Examples:

* I gave the book to her. (Her is the recipient of the action of giving)

* The gift is for her. (Her is the object of the preposition "for")

Here's a quick table to summarize:

| Pronoun | Use | Example |

|---------|----------------------------------------|------------------------------------------------------------------------|

| She | Subject of the sentence | She is a doctor. |

| Her | Object of the verb or preposition | I gave the gift to her.
The book belongs to her. |

Remember:

* "She" is used when the noun or pronoun is performing the action.

* "Her" is used when the noun or pronoun is receiving the action.

If you're ever unsure, try substituting "she" with "he" or "her" with "him". If the sentence still makes sense, then you've likely used the correct pronoun.
