How do you find a parts of speech in the sentence?

In English, parts of speech refer to the job that each Word does in a sentence. For example: a noun is a person (Maria, David, teacher, scientist); a place (Boston, America, Brazil, New York); or a thing (book, house, bus, computer). A noun can be the subject in a sentence-- the person who does the action. Or it can be object-- the person who receives the action. A verb is generally a Word that shows what action was performed: to run, to dance, to eat, to study. In an English sentence, you musthave a subject and a verb. So: David studied for eight hours. David is the subject, and David is a noun. (You can also use a pronoun-- a pronoun substitutes for a noun-- I could say He studied for eight hours.) The verb is studied-- that is the action that was performed.

In order to find the parts of speech in a sentence, look at what they are doing: are they showing WHO did it? Are they showing what the ACTION was? That is the first step. Then you can look for the object: David hugged Maria. David is the doer. The receiver of the action is Maria. I could go on, but I hope this gets you started. I enclose a link to a good explanation of each part of speech and what it does in a sentence.
