When do you use and to combine sentences?

You use "and" to combine sentences when you want to show that two or more things are happening or are true at the same time, or that one thing happens or is true, and then another thing happens or is true.

Here are some specific cases when "and" is used to combine sentences:

1. To show two events happening in sequence:

* "I went to the store and bought some milk."

2. To show two events happening simultaneously:

* "She was singing and dancing at the same time."

3. To list items or ideas:

* "We need to buy eggs, milk, and bread."

* "The book was interesting, well-written, and thought-provoking."

4. To show two things are true:

* "He is a good student and a talented musician."

5. To combine two sentences with similar meaning:

* "The sun is shining and it's a beautiful day."

6. To show a contrast or exception:

* "I love pizza, and I don't even like tomatoes."

Important note: When using "and" to combine sentences, make sure that the resulting sentence is grammatically correct and makes sense. You may need to add commas, semicolons, or other punctuation to help clarify the relationship between the sentences.
