Relative Clauses, Causatives & Connectives: Rules & Uses

Unit 17 of English covers relative clauses (defining/non-defining), causatives (make/let/have), and connectives (linking words/phrases) with clear rules, examples, and exam-focused practice for NEB Class 12.

TAKEAWAYS:

  • Relative clauses join two sentences using who, which, that, whose, where, when (defining vs. non-defining).
  • Causatives (make, let, have) show who makes someone do something (active vs. passive forms).
  • Connectives (however, moreover, in addition) link ideas smoothly in writing.
  • Commas separate non-defining clauses; defining clauses have no commas.
  • NEB exams test error correction, sentence transformation, and essay writing using these structures.

Relative Clauses

Relative clauses add extra information about a noun. They start with relative pronouns (who, which, that, whose, where, when).

1. Defining Relative Clauses (Essential)

  • Definition: Provide essential information (no commas).
  • Example:
    • The book that is on the table is mine.
    • The man who called you is my teacher.

2. Non-Defining Relative Clauses (Non-Essential)

  • Definition: Add extra (non-essential) info (use commas).
  • Example:
    • My brother, who lives in Kathmandu, is a doctor.
    • The Eiffel Tower, which is in Paris, is very tall.

Key Rules:

Relative Pronoun Refers to Example
who People (subject) The girl who sings is my sister.
whom People (object) The man whom I met is kind.
whose Possession The boy whose bag is red is here.
which Things (subject/object) The car which is blue is mine.
that People/things The book that I read is good.
where Place The place where I live is quiet.
when Time The day when we met was special.

Common Mistakes:

❌ The man who I met yesterday is my uncle. (Incorrect: whom needed) ✅ The man whom I met yesterday is my uncle.

❌ The house, which is very big, is empty. (Incorrect: that is better for defining) ✅ The house that is very big is empty.


Worked Example: Original: I have a friend. He lives in Pokhara. Combined (defining): I have a friend who lives in Pokhara. Combined (non-defining): I have a friend, who lives in Pokhara, since childhood.


Causatives (Make, Let, Have)

Causatives show who makes someone do something.

1. Make (Force/Require)

  • Structure: Subject + make + object + base verb
  • Example:
    • My mother makes me study every day.
    • The teacher made us write an essay.

2. Let (Allow/Permit)

  • Structure: Subject + let + object + base verb
  • Example:
    • My father lets me watch TV after homework.
    • She let her dog sleep on the couch.

3. Have (Get Someone to Do)

  • Structure: Subject + have + object + past participle
  • Example:
    • I had my brother repair the bike.
    • She had her hair cut yesterday.

Passive Causatives:

  • Example:
    • I had my car repaired. (Active: I had a mechanic repair my car.)
Causative Active Form Passive Form
Make She makes him work hard. He is made to work hard.
Let They let us go early. We were let go early.
Have I had my phone fixed. My phone was had fixed. (Rare)

Worked Example: Original: The boss ordered. The workers cleaned the office. Causative: The boss made the workers clean the office.


Connectives (Linking Words & Phrases)

Connectives join ideas, sentences, or paragraphs smoothly.

Types of Connectives:

  1. Addition: and, also, moreover, furthermore, in addition
    • She is intelligent. Moreover, she is kind.
  2. Contrast: but, however, although, despite, whereas
    • He is rich. However, he is unhappy.
  3. Cause/Effect: because, since, as a result, consequently
    • She studied hard. As a result, she passed.
  4. Time: when, while, after, before, meanwhile
    • I was reading when the phone rang.
  5. Purpose: so that, in order to
    • He works hard so that he can succeed.

Common Mistakes:

❌ She is tired, but she went to school. (Correct: although) ✅ She is tired, although she went to school.

❌ I like tea and coffee. (Correct if both are true) ✅ I like tea, but I prefer coffee.


Worked Example: Original: It rained. We stayed home. Combined (cause): Since it rained, we stayed home. Combined (contrast): It rained, yet we went out.


Exam Tip: How to Score Full Marks

  1. Relative Clauses:

    • Error Correction: Spot missing commas or wrong pronouns (who vs. whom).
    • Sentence Transformation: Combine two sentences using who, which, that.
    • Essay Writing: Use non-defining clauses for extra details (The Himalayas, which are the world’s highest mountains, attract many climbers.).
  2. Causatives:

    • Fill in the Blanks: Choose make, let, or have correctly.
    • Rewrite Sentences: Convert active to passive (She made him clean → He was made to clean.).
    • Grammar Exercises: Avoid mixing tenses (❌ She makes me study yesterday. ✅ She made me study yesterday.).
  3. Connectives:

    • Paragraph Writing: Use however, moreover to link ideas logically.
    • Comprehension Questions: Identify connectives that show contrast, cause, or addition.
    • Proofreading: Ensure connectives match the tone (formal: therefore; informal: so).
