Sentence Structure

A simple sentence has one subject and one verb. It expresses a complete thought. For example, "The dog barks."

A compound sentence joins two simple sentences. Use conjunctions like "and," "but," or "or." For example, "The dog barks, and the cat meows."

A complex sentence has one main clause and one or more dependent clauses. Dependent clauses cannot stand alone. For example, "The dog barks when the mailman arrives." The main clause is "The dog barks." The dependent clause is "when the mailman arrives."

Parts Of Speech

Nouns name people, places, things, or ideas. Examples include dog, city, and happiness. Nouns can be singular or plural. For example, book becomes books. Some nouns are proper, like John or Paris. Proper nouns always start with a capital letter.

Verbs show actions or states of being. Examples are run, jump, and is. Verbs change form to show time. For example, run becomes ran. Some verbs are irregular like go and went. Verbs are essential in every sentence.

Adjectives describe nouns. They answer questions like which one, what kind, and how many. Examples include blue, tall, and five. Adjectives make sentences more interesting. They provide more details. For instance, big house or red apple.

Adverbs describe verbs, adjectives, or other adverbs. They answer questions like how, when, and where. Examples are quickly, yesterday, and here. Many adverbs end in -ly. For example, slowly or happily. Adverbs make actions clearer.

Punctuation Rules

Periods end sentences. They show that a thought is complete. Use a period after every sentence. Do not forget this rule. It is very important. You can also use periods in abbreviations. For example, "Dr." or "U.S.A."

Commas separate items in a list. For example, apples, oranges, and bananas. They also come before conjunctions like "and" or "but." Use a comma after introductory words. For example, "First, let's review." Commas also set off non-essential information. For example, "My friend, who is a doctor, lives in New York."

Semicolons link related sentences. They can replace conjunctions like "and" or "but." For example, "I went to the store; I bought milk." Semicolons also separate items in a complex list. For example, "We visited Paris, France; Rome, Italy; and Berlin, Germany."

Colons introduce lists or explanations. For example, "You need: a pen, paper, and a ruler." Use colons before quotes. For example, She said: "Hello." Colons also link related sentences. For example, "She had one goal: to win."

Verb Tenses

Past tense describes actions that already happened. For example, "I went to the store." The verb "went" shows the action is over. Another example is, "She played soccer yesterday." The word "played" means the game is finished. We use past tense to talk about events from the past.

Present tense describes actions happening now. For example, "I am reading a book." The verb "am" shows the action is happening now. Another example is, "They play soccer every day." The word "play" means the action happens regularly. Present tense helps us talk about current events.

Future tense describes actions that will happen. For example, "I will go to the store." The phrase "will go" shows the action is in the future. Another example is, "She will play soccer tomorrow." The words "will play" mean the game has not started yet. We use future tense to talk about what is coming.

Subject-verb Agreement

A singular subject needs a singular verb. A plural subject needs a plural verb. For example, "She reads books" is correct. "They read books" is also correct. Mistakes can happen if you mix them up.

When subjects are joined by "and," use a plural verb. For example, "Tom and Jerry are friends." When subjects are joined by "or" or "nor," the verb agrees with the subject closest to it. For example, "Either the cat or the dogs are outside." "Neither the dogs nor the cat is outside."

Pronouns And Antecedents

Personal pronouns include words like I, you, he, she, it, we, and they. These pronouns take the place of nouns. For example, he replaces a man's name. It makes sentences shorter and clearer.

Possessive pronouns show ownership. Examples are my, your, his, her, its, our, and their. These pronouns do not need apostrophes. For instance, her book is correct. It shows that the book belongs to her.

Relative pronouns connect clauses or phrases to nouns. Common ones are who, whom, whose, which, and that. For example, "The boy who plays soccer is my friend." The word who connects the clauses.

Modifiers

Adjectives describe nouns. They tell more about a person, place, or thing. For example, the word "happy" in "happy child." Adjectives can also tell how many. Like "three" in "three cats." Adjectives often come before the noun they describe.

Adverbs describe verbs, adjectives, or other adverbs. They tell how, when, where, or how much. For example, "quickly" in "runs quickly." Adverbs often end in "-ly." But not all adverbs do. Words like "very" and "well" are also adverbs.

Misplaced modifiers can confuse. They describe the wrong word in a sentence. For example, "She almost drove her kids to school every day." This means she did not quite drive them. Correct: "She drove her kids to school almost every day." Always place modifiers near the word they describe.

Common Grammatical Mistakes

Run-on sentences happen when two sentences join without punctuation. This makes reading hard. Readers get confused. It is important to use a period or a comma with a conjunction. This can help separate ideas.

Fragmented sentences lack a subject or a verb. They look like sentences but are incomplete. Always check that each sentence has a subject and a verb. This ensures clarity and completeness.

Comma splices occur when two sentences are joined by a comma. This is incorrect. Use a period or a conjunction instead. This creates clear and correct sentences.
