Unit 4: Language and Grammar Skills

---

1. Sentence Structure and Types

Sentences are the building blocks of communication. They can be classified based on purpose, structure, and complexity.

1.1 Types of Sentences by Purpose

1.2 Types of Sentences by Structure

Sentences can be simple, compound, complex, or compound-complex.

Worked Example: Business Email Incorrect: "Nepal Bank requested payment by 15th. We need to confirm the transfer."

Corrected (Compound): "Nepal Bank requested payment by 15th, and we need to confirm the transfer."

Corrected (Complex): "Although Nepal Bank requested payment by 15th, we need to confirm the transfer."

2. Tenses: The 12 Tenses Explained

Tenses show time and aspect (action completion). Mastering them is crucial for business communication (e.g., loan agreements, project timelines).

2.1 Simple vs. Continuous vs. Perfect vs. Perfect Continuous

2.2 Common Tense Mistakes in Business Writing

• Mixing tenses in a sentence: Incorrect: "The loan agreement states that the interest rate will be 8% and will apply from next month." Corrected: "The loan agreement states that the interest rate is 8% and will apply from next month."

• Using present perfect for unfinished past actions: Incorrect: "I have visited Kathmandu last year." (Past simple is correct.) Correct: "I visited Kathmandu last year."

Worked Example: Loan Agreement Scenario: A bank offers a loan with an interest rate that starts now and continues for 5 years. Correct Tense Usage:

• "The loan is approved at an annual interest rate of 10%. You will have paid the full amount by 2028."

---

3. Modals: Expressing Obligation, Possibility, and Advice

Modals (can, could, may, might, must, should, ought to, will, would, shall, should) add nuance to sentences.

3.1 Modals of Obligation

3.2 Modals of Possibility

Worked Example: Customer Complaint Incorrect: "Your delivery is late. It should arrive yesterday."

Corrected: "Your delivery is late. It might have been delayed due to traffic."

---

4. Prepositions: Common Errors and Fixes

Prepositions (in, on, at, by, for, with, from, to, about) indicate time, place, or relationship. Misusing them can change meaning entirely.

4.1 Time Prepositions

4.2 Place Prepositions

Worked Example: Travel Plans Incorrect: "I will meet you at the airport in 8 PM."

Corrected: "I will meet you at the airport at 8 PM."

---

5. Punctuation: Commas, Apostrophes, and Quotation Marks

Punctuation clarifies meaning and improves readability.

5.1 Commas: Rules and Mistakes

5.2 Apostrophes: Possession vs. Plural

Worked Example: Business Memo Incorrect: "The employees’ suggestions were discussed in the meeting."

Corrected: "The employees’ suggestions were discussed in the meeting." (Correct for multiple employees.)

---

6. Common Errors in English Writing

6.1 Subject-Verb Agreement

6.2 Articles (A/An/The)

6.3 Word Confusion

Worked Example: Error Correction Incorrect: "Their going to the market because they’re hungry."

Corrected: "They’re going to the market because they’re hungry." (or "Their going to the market because it’s raining.")

---

7. Paragraph Structure: Topic Sentence, Details, and Conclusion

A well-structured paragraph has:

1. Topic sentence (main idea).
2. Supporting details (evidence, examples).
3. Conclusion (summarizes or links to the next point).

Worked Example: Business Report Paragraph Topic: The impact of digital payments on Nepal’s economy. Paragraph: Digital payments, such as those facilitated by eSewa and Khalti, have revolutionized Nepal’s economy. These platforms allow instant transactions, reducing the need for cash and lowering transaction costs. According to the Central Bank of Nepal, digital payments grew by 40% in 2022, benefiting both consumers and businesses. Moreover, they have increased financial inclusion, allowing rural populations to access banking services. While challenges like internet dependency remain, the long-term benefits for economic growth are undeniable.

8. Formal vs. Informal Writing

Worked Example: Formal vs. Informal Email Formal (Bank Manager to Employee):

Subject: Urgent: Project Deadline Extension

Dear Ms. Thapa,

I hope this email finds you well. As discussed, the project deadline for the **Nepal Bank Loan Analysis Report** has been extended to **June 15th** due to unforeseen circumstances. Please ensure all data is verified and submitted by the new deadline.

Best regards,
[Your Name]
Loan Department Manager

Informal (Friend on WhatsApp):

Hey Bulbul! 😊
So the report deadline got pushed to June 15th. No stress, we’ve got time! Let’s split the work—you do the graphs, I’ll handle the intro. Let me know if u need help!

In the Real World

1. eSewa/Khalti: Prepositions and Modals in Transaction Messages

   • Prepositions: "Your payment of Rs. 500 was processed at 3:45 PM on May 10."
   • Modals: "You must update your password every 90 days for security."
   • Why it matters: Clear communication prevents fraud and reduces customer complaints.

2. Daraz: Tenses in Order Tracking

   • Past simple: "Your order was shipped yesterday."
   • Present continuous: "Your order is being processed by our warehouse."
   • Future perfect: "By tomorrow, your order will have been delivered."
   • Why it matters: Customers expect real-time updates, and tense errors create confusion.

3. NTC/Ncell: Commas and Articles in Service Notices

   • Incorrect: "Service will be suspended in Kathmandu at 10 PM."
   • Corrected: "Service will be suspended in Kathmandu at 10 PM." (Oxford comma for clarity.)
   • Why it matters: Ambiguous notices lead to customer frustration and legal risks.

4. Bank Loans: Modals of Obligation

   • "Borrowers must repay the loan within 5 years." (Legal document.)
   • "You should consider a lower interest rate if possible." (Customer advisor.)
   • Why it matters: Clarity in loan terms prevents disputes and defaults.

Exam Tip

1. For Case-Based Questions:

   • Highlight tenses, modals, and prepositions in the given text. For example, if a case mentions a loan agreement, identify whether the verbs are in simple present (rules) or future perfect (completion).
   • Correct 5 errors (e.g., subject-verb agreement, article misuse) in a paragraph. Focus on common mistakes like "their/there/they’re" or "its/it’s."

2. For Writing Sections:

   • Use formal language in emails/reports (e.g., "I would appreciate it if..." instead of "Please do...").
   • Structure paragraphs with a topic sentence + details + conclusion. For example, if writing about digital payments, start with a general statement, then list benefits (eSewa/Khalti), and end with a forward-looking conclusion.

3. For Grammar Fill-in-the-Blanks:

   • Remember:
     • Must/may/might for obligation/possibility.
     • At/in/on for time/place (use at for exact times, in for months/years).
     • Their/there/they’re and its/it’s are top-scoring points.

4. For Error Identification:

   • Look for:
     • Missing commas in compound sentences.
     • Incorrect articles (e.g., "a" vs. "an").
     • Subject-verb agreement errors (e.g., "The team is working" vs. "The team are arguing").

5. Real-World Application:

   • If the exam gives a business scenario (e.g., a complaint about NTC’s service), rewrite the sentence correctly using modals (e.g., "The service might have been delayed due to maintenance").
   • For paragraph writing, use prepositions to describe time/place (e.g., "The meeting will take place at 2 PM on Friday in the conference room").

Final Note: Grammar is not just rules—it’s communication. In exams, focus on accuracy, but in real life, clarity matters most. For example, a bank’s loan agreement must use precise modals ("you must repay"), while a Pathao rider’s chat can be informal ("ride gayab hunchha!" 😅). Always match your tone to the audience!

In the real world

• Nepal Bank Loan Agreements: Use perfect continuous tense ("You have been a valued customer since 2020") and modals of obligation ("You must repay within 5 years") to outline terms clearly. Misusing tenses here (e.g., mixing present perfect with past simple) can void the contract.
• Pathao Driver Alerts: Imperative sentences ("Cancel the ride if the passenger is uncooperative") paired with future continuous ("I will be at your location in 5 minutes") ensure safety and clarity. Drivers often confuse "will be doing" (ongoing action) with "will do" (single action).
• Daraz Customer Reviews: Exclamatory sentences ("What a terrible experience! The product arrived damaged!")* and interrogative tags ("You didn’t receive your order, did you?")* drive engagement. Sellers respond with conditional modals ("If you could share photos, we’ll refund you immediately").
