Basics of Grammar

Subject-Verb Agreement

Subject-Verb Agreement is a fundamental grammar rule that ensures the subject and verb in a sentence match in number (singular or plural). A singular subject requires a singular verb, while a plural subject requires a plural verb. This agreement is essential for clear and grammatically correct communication.

Examples:

Singular Subject with Singular Verb:

  • The dog barks at strangers.

  • She plays the piano beautifully.

  • He runs in the morning.


Plural Subject with Plural Verb:

  • The dogs bark at strangers.

  • They play soccer every weekend.

  • The students study diligently for exams.


Singular Subject with Singular Verb (Third Person Singular):

  • He works at a software company.

  • She loves reading books.

  • It rains during the monsoon.


Singular Subject with Singular Verb (Indefinite Pronouns):

  • Everybody enjoys a good laugh.

  • Nobody likes cold coffee.

  • Somebody has left their bag behind.


Compound Subjects with Plural Verb:

  • Tom and Jerry are good friends.

  • Pizza and pasta are my favorite dishes.


Collective Nouns:

  • The committee meets every Monday. (Singular verb because the committee acts as a single unit.)

  • The jury deliberates on the case. (Singular verb because the jury acts as one entity.)


Remember, subject-verb agreement is crucial in all types of writing and speaking. Errors in subject-verb agreement can lead to confusion and affect the clarity of your communication. Always double-check that your subjects and verbs match in number to avoid these common grammatical mistakes.




Punctuation Rules


Punctuation is a set of marks used in writing to clarify meaning, indicate pauses, and organize thoughts. Proper use of punctuation is crucial for effective communication and can significantly impact the clarity and coherence of your writing.


Examples:


Comma (,):

  • I went to the store, and I bought some groceries. (Use a comma before a coordinating conjunction to separate two independent clauses.)

  • In the morning, I like to take a walk. (Use a comma after an introductory phrase or clause.)

  • My brother, John, is an engineer. (Use commas to set off non-essential information, also known as an appositive.)


Period (.)

  • I finished my assignment. (Use a period at the end of a declarative sentence.)

  • The train will arrive at 3:00 p.m. (Use a period to end a sentence that contains an abbreviation.)


Question Mark (?):

  • Did you finish your homework? (Use a question mark at the end of an interrogative sentence.)

  • What time is the meeting? (Use a question mark for direct questions.)


Exclamation Mark (!):

  • Wow! That was an amazing performance! (Use an exclamation mark to show strong emotion or exclamatory statements.)


Semicolon (;):

  • I have an exam tomorrow; I need to study tonight. (Use a semicolon to connect two closely related independent clauses without a coordinating conjunction.)


Colon (:):

  • There are three colors in the flag: red, white, and blue. (Use a colon to introduce a list or to separate two related clauses, where the second explains or expands on the first.)


Quotation Marks (" "):

  • "I will be there soon," she said. (Use quotation marks to enclose direct speech.)

  • The movie "Titanic" is a classic. (Use quotation marks for the titles of short works like articles, poems, or movies.)


Apostrophe ('):

  • It's a beautiful day. (Use an apostrophe to show contraction, e.g., "it is" becomes "it's.")

  • John's car is parked outside. (Use an apostrophe to indicate possession.)


Hyphen (-):

  • The two-year-old child is very active. (Use a hyphen to join compound adjectives before a noun.)

  • The mother-in-law is visiting this weekend. (Use a hyphen in certain compound words.)


These are some of the essential punctuation rules, but there are more nuances and guidelines to explore. Proper punctuation can significantly enhance the flow and understanding of your writing, so take the time to learn and apply these rules effectively.



Lesson: Articles (a, an, the)

Articles are small but significant words used before nouns to provide information about the specificity or generalization of the noun. Understanding when and how to use articles is essential for clear and accurate communication. Examples:

Definite Article "the":

  • I saw the movie last night. (Refers to a specific movie that the speaker watched.)

  • The Eiffel Tower is in Paris. (Refers to a specific landmark known to both the speaker and listener.)


Indefinite Article "a" (used before consonant sounds):

  • I ate a delicious meal. (Refers to any unspecified delicious meal.)

  • She adopted a cute puppy. (Refers to any unspecified cute puppy.)


Indefinite Article "an" (used before vowel sounds):

  • She is an excellent dancer. (Refers to any unspecified excellent dancer.)

  • He bought an interesting book. (Refers to any unspecified interesting book.)


No Article (Zero Article):

  • Cats are my favorite animals. (No article is used when speaking in a general sense about a plural countable noun.)

  • I like to read books. (No article is used when speaking in a general sense about a plural countable noun.)


Using Articles with Adjectives:

  • I saw a beautiful sunset. (The indefinite article "a" is used before the adjective "beautiful.")

  • She wants to buy the red dress. (The definite article "the" is used before the adjective "red.")


Using Articles with Singular and Plural Nouns:

  • He is a doctor. (Indefinite article "a" is used before the singular noun "doctor.")

  • They are the doctors. (Definite article "the" is used before the plural noun "doctors.")


Using Articles with Uncountable Nouns:

  • Can you pass me the salt? (The definite article "the" is used before the uncountable noun "salt.")

  • I need some water. (The indefinite article "some" is used before the uncountable noun "water.")


Remember, using the correct article can significantly impact the meaning of a sentence. Pay attention to the specificity of the noun and whether it is countable or uncountable to determine which article to use. With practice, you'll become more proficient in using articles accurately in your writing and speaking.



Lesson: Verb Tenses
