Subject -- there are two basic types of nouns or pronouns: subjects and objects.  A subject is the person, place or thing thatis "performing" the action in the sentence.  In "I feel pretty," or"Jack and Jill went up the hill," or "New York is a wonderful town," or "Honesty is the best policy,"  the pronoun "I" and the nouns "Jack"  "Jill"  "New York" and "honesty" are all subjects. 

Object -- there are two basic types of nouns or pronouns: subjects and objects.  A subject is the person, place or thing thatis "preforming" the action in a sentence.  The object is the person,place or thing that is "receiving" the action, or the person, place or thingto whom, for whom,  to which or for which the action is being performed.  In the sentences, "Goober pumps the gas" or "Gomer never listens to Sgt Carter", or "I work for Mr. Douglas", "Goober", "Gomer" and "I" are subjects.  "Sgt Carter", "gas" and "Mr. Douglas" are objects.  Objects come in avariety of flavors, to explore them, take a look at "direct objects," "indirect objects".

Indirect Object (Pronouns) -- an indirect object is a person to whom the action is being performed.   For example, in the sentences "I sent the book to John" or "Mary gave her mother a present", the nouns "John"and "mother" are indirect objects.  In "Tell me what you know," thepronoun "me" is an indirect object.

Direct Object (Pronouns) -- a direct object is the person, place or thing "receiving" the action in the sentence.  For example, in "Austin Powers:  the Spy Who Shagged Me," the pronoun "me" is the direct object.  In the sentence "If you build it, they will come," the pronoun "it" is the direct object.

Pronoun -- a pronoun is a small word that takes the place of a noun. It would get very tedious to tell stories without pronouns.  Imaginethe following  "The teacher came into class and told the students thatthe teacher would give the students the test a day early because the teacherthought that the students were ready for the test".  Isn't is much nicerto say "The teacher came into class and told the students that he would givethem the test a day early because he thought that they were ready for it"? Thank goodness for pronouns like "he,"  "them," and "it"!
