"We"
* Subject of a verb: "We" is used when it's the one performing the action.
* Example: "We went to the park."
* Nominative case: This means it functions as the subject of a sentence or clause.
"Us"
* Object of a verb: "Us" is used when it's the one receiving the action.
* Example: "The teacher gave us homework."
* Object of a preposition: "Us" is used after prepositions like "to," "for," "with," etc.
* Example: "She sent a postcard to us."
* After "than" or "as" in comparisons:
* Example: "They are taller than us."
Important Considerations
* Compound subjects and objects: If a phrase includes "we" or "us" along with other nouns or pronouns, the rule still applies.
* Example: "John and we are going to the movies." (Correct, "we" is the subject)
* "It is we" vs. "It is us": The traditional grammatical rule dictates "It is we," but "It is us" is becoming increasingly common in informal speech.
Tips to remember:
* Replace with "I" or "me": If you can substitute "I" for "we" or "me" for "us" and the sentence still makes sense, you're using the correct pronoun.
* Think about the action: Who is doing the action? Who is receiving the action?
