Pronouns of Subject Case: Pronomes do Caso do Sujeito.

The subject of a sentence is the person or thing that performs the action of the verb. The subject pronoun replaces this person or thing.

	Subject Pronouns
	Singular		Plural
1st person	I		we
2nd person	you		you
3rd person	he she it		they

Notes:

1. In English, unlike some languages, you cannot have a sentence without a subject. I love you. Where is he?
    
2. I is always capitalized, even if it doesn't start the sentence: Where is the book I bought?
    
3. In English, there is only one word for the second person, whether it is singular or plural, familiar or formal, masculine or feminine.*(gender)
    
4. Most English nouns do not have gender. When talking about an object, the word it is used in English. He and she are only used when referring to people and sometimes animals. They is used to refer to more than one person or thing.

*Sometimes there is a difference between the second person singular and plural, but it is not proper grammar. In the south of the United Station, "you all" or "y'all" is commonly used when talking to more than one person. In northeastern American cities, you might hear "youse." And in informal situations, "you guys" is commonly used.
