The Word 'and' is a conjunction. It joins 2 or more Words or phrases together. 'And' usually appears inside a sentence, but it can be the first Word of a sentence as long as the sentence before is a complete thought and the sentence beginning with 'And' explains something not included in the other sentence, something that gives more detail. Here are some example sentences:
- I felt hot and dirty after weeding the garden.
- The girl ordered a hamburger, french fries, and a coke.
- The man explained he didn't think the accident was his fault. And besides, the other driver ran a stop sign while going 20 mph over the speed limit. (notice that 'while' could be replaced by 'and was'... but then, you don't need the And at the beginning of the sentence).
- The boy finished his math problems, the chapter reading, and his spelling assignment.
- For breakfast she had cereal and milk.
