Clauses & Their Uses in CUET Grammar Questions: 100 MCQs

Clauses & Their Uses in CUET Grammar Questions

Basic Theoretical Concepts

What is a Clause?

A clause is a group of words containing a subject and a predicate (verb) that conveys a statement, question, or idea. Clauses are the building blocks of sentences and are tested extensively in CUET English for grammatical accuracy, coherence, and function.

Types of Clauses

  1. Independent (Main) Clause:
    • Stands alone as a complete sentence.
    • Contains a subject and predicate expressing a complete thought.
    • Example: “She studies hard.”
    • Use: Forms the core of a sentence or joins with other clauses.
  2. Dependent (Subordinate) Clause:
    • Cannot stand alone; depends on an independent clause for meaning.
    • Begins with subordinating conjunctions (e.g., because, although, if) or relative pronouns (e.g., who, which, that).
    • Example: “Because she studies hard.”
    • Use: Adds detail, condition, reason, or description.

Subtypes of Dependent Clauses

  1. Noun Clause:
    • Acts as a noun (subject, object, complement).
    • Introduced by “that,” “what,” “who,” “whether,” etc.
    • Example: “What she said surprised me.” (Object)
    • Use: Replaces a noun in the sentence.
  2. Adjective (Relative) Clause:
    • Modifies a noun, providing additional information.
    • Introduced by relative pronouns (who, whom, whose, which, that).
    • Example: “The book that I borrowed is excellent.”
    • Use: Describes or identifies a noun.
  3. Adverb Clause:
    • Modifies a verb, adjective, or adverb, answering “how,” “when,” “where,” “why,” or “to what extent.”
    • Introduced by subordinating conjunctions (e.g., because, since, if, when).
    • Example: “She left early because she was tired.”
    • Use: Shows cause, time, condition, etc.

Key Rules for Clauses in CUET

  • Correct Conjunctions: Use appropriate subordinating conjunctions or relative pronouns to connect clauses logically.
  • Tense Agreement: Ensure verb tenses align between main and subordinate clauses (e.g., “If I study, I will pass” – present, future).
  • Punctuation: Use commas for non-essential clauses (e.g., “My brother, who lives in Delhi, is a doctor”) but not for essential ones (e.g., “The man who called me is here”).
  • Parallelism: Maintain consistent structure in clauses within a sentence.

CUET Relevance

CUET tests clauses through:

  • Error Spotting: Identifying misuse of conjunctions, tense shifts, or clause structure errors.
  • Sentence Improvement: Correcting or rephrasing clauses for clarity and grammatical accuracy.
