English Grammar & Linguistics: Parts of Speech, Sentence Structure & Usage

Core Concepts in English Grammar & Linguistics

1. What is Grammar?

Grammar is the structured system of rules governing how words combine to form sentences in a language. It includes:

• Morphology: Study of word formation (e.g., un- in unhappy).
• Syntax: Rules for sentence structure (e.g., subject-verb-object order).
• Phonology: Sound patterns (not covered here but critical for pronunciation).
• Semantics: Meaning in language (e.g., connotations of economical vs. cheap).

Why it matters: Grammar ensures clarity, correctness, and precision in communication—key for exams, reports, and professional writing.

2. Parts of Speech (Word Classes)

Words are categorized based on their function in sentences. Mastering these helps analyze texts and write accurately.

Worked Example: Analyze the sentence: "The quick brown fox jumped over the lazy dog yesterday."

• Nouns: fox, dog
• Adjectives: quick, brown, lazy
• Verb: jumped
• Adverb: yesterday
• Article: the

Common Mistakes:

• Confusing adjectives and adverbs (*She runs fast [adverb] vs. a fast runner [adjective]).
• Overusing very (e.g., very unique → unique or highly unique).

---

3. Sentence Structure

Sentences are the building blocks of communication. Their structure affects meaning and tone.

A. Types of Sentences by Purpose

B. Sentence Types by Structure

Worked Example (Compound-Complex): "Because the traffic was heavy, I left early, and I arrived on time."

• Dependent clause: Because the traffic was heavy
• Independent clauses: I left early + I arrived on time

Real-World Tie-In:

• Pathao’s Ride Request: "If you select ‘Go,’ the driver will arrive soon, and you’ll get a real-time update." (Compound-complex sentence for clarity in app instructions.)

---

4. Subject-Verb Agreement

Subjects and verbs must agree in number (singular/plural) and person (first/second/third).

Worked Example:

• Correct: The list of items is long. (Subject: list [singular])
• Incorrect: The list are long. (❌)

Real-World Tie-In:

• Ncell’s SMS: "Your balance is low." (Singular agreement for clarity in notifications.)

---

5. Tenses: Verb Forms for Time

Tenses indicate when an action occurs. Mastering them is critical for writing narratives, reports, and emails.

Worked Example (Mixed Tenses): "By the time you arrive (present), I will have finished (future perfect) my report, and I will be reviewing (future continuous) the data."

Real-World Tie-In:

• Daraz Order Confirmation: "Your order has been shipped (present perfect). You will receive (future) it by Friday."
• NEPSE Stock Alert: "The share price rose (past) yesterday, but it will continue (future) to fluctuate today."

---

6. Active vs. Passive Voice

When to Use Passive:

• When the doer is unknown or unimportant (The accident was reported at 5 PM).
• In scientific/academic writing (The experiment was conducted in 2023).

Worked Example:

• Active: Khalti processes payments quickly.
• Passive: Payments are processed quickly by Khalti.

Real-World Tie-In:

• NTC’s Service Notice: "The outage was caused by heavy rain." (Passive to focus on the reason, not the doer.)

---

7. Common Grammar Pitfalls

Worked Example (Dangling Modifier):

• Incorrect: After finishing the report, the deadline was extended. (What extended the deadline?)
• Correct: After I finished the report, the deadline was extended.

---

8. Writing Skills: Formal vs. Informal English

Real-World Examples:

• Formal: eSewa’s Terms of Service: "Users are required to adhere to the privacy policy."
• Informal: WhatsApp Message: "Hey, don’t forget to pay the bill!"

---

In the Real World

1. Khalti’s Transaction Notifications:

   • Grammar in Action: Uses simple present (Your balance is updated) and passive voice (Payment was processed) for clarity and professionalism.
   • Why it works: Passive voice avoids blaming the system ("We processed..." vs. "Payment was processed..."), making users feel the action is neutral and automatic.

2. Pathao’s Ride Request System:

   • Sentence Structure: Compound-complex sentences guide users: "If you select ‘Go,’ the driver will arrive soon, and you’ll see their location on the map."
   • Adverbs: "Quickly accept the ride to avoid delays." (Adverbs modify verbs for urgency.)

3. Ncell’s Customer Care Emails:

   • Subject-Verb Agreement: "Your data package has expired." (Singular agreement for clarity.)
   • Formal Tone: Avoids contractions ("Please do not hesitate to contact us") to maintain professionalism.

4. NEPSE Stock Alerts:

   • Tenses: Mixes past ("The share rose yesterday") and future ("It will open at 11 AM") to provide context.
   • Passive Voice: "The record was updated automatically." (Focuses on the action, not the system.)

5. Daraz’s Order Tracking:

   • Conditional Sentences: "If you pay now, your order will ship today." (Present simple for conditions, future for results.)

Exam Tip

This unit is heavily tested in TU’s English I exams through:

1. Grammar Identification: Spot the error in a sentence (e.g., subject-verb disagreement, misplaced modifiers).

   • Example Question: "Which sentence is grammatically correct?" A) The team are playing well. B) The team is playing well. Answer: B (Collective noun + singular verb.)

2. Sentence Transformation: Convert active to passive or vice versa.

   • Example: Change "The bank approved the loan." to passive voice.
   • Answer: "The loan was approved by the bank."

3. Parts of Speech: Label parts of a sentence.

   • Example: In "She quickly finished her homework," identify the adverb.
   • Answer: quickly.

4. Tense Usage: Fill in the blank with the correct tense.

   • Example: "By next month, I will have completed the project." (Future perfect.)

5. Writing Tasks: Write a formal email or notice using correct grammar and tone.

   • Tip: Always use formal English in exams unless specified otherwise. Avoid contractions and slang.

Pro Tip for Full Marks:

• For grammar questions: Underline the incorrect part and rewrite it correctly.
• For transformations: Show all steps (e.g., active → passive: identify object → rearrange).
• For writing: Use complex sentences (compound/complex) and varied vocabulary to impress examiners.
