What is the Difference Between Relative Clause and Subordinate Clause?

🆚 Go to Comparative Table 🆚

The main difference between a relative clause and a subordinate clause lies in their role within a sentence and how they are introduced.

A relative clause is a type of subordinate clause that modifies a noun or pronoun and begins with a relative pronoun (who, whom, whose, which, or that) or a relative adverb (when, where, or why). Relative clauses can be either defining or non-defining. Defining relative clauses provide essential information about the noun or pronoun, while non-defining relative clauses provide extra information that is not necessary for the main idea of the sentence. For example:

  • Defining relative clause: "The person who called was my sister." (The clause provides essential information about the person.)
  • Non-defining relative clause: "My sister, who has red hair, is a talented musician." (The clause provides extra information about my sister.)

A subordinate clause is a clause that cannot stand alone as a complete sentence and needs to be attached to an independent clause. Subordinate clauses can function as an adverb, adjective, or noun within a sentence. They are often introduced by subordinating conjunctions, such as "because," "if," or "that". For example:

  • Adverb clause: "I went to the store so that I could buy food." (The clause modifies the verb "went" and is introduced by "so.")
  • Adjective clause: "She is the person whom I told you about." (The clause modifies the noun phrase "the person" and is introduced by "whom.")
  • Noun clause: "What he said was amazing." (The clause functions as a noun and is introduced by "what.")

In summary, a relative clause is a specific type of subordinate clause that modifies a noun or pronoun and begins with a relative pronoun or adverb, while a subordinate clause can function as an adverb, adjective, or noun within a sentence and is introduced by a subordinating conjunction.

Comparative Table: Relative Clause vs Subordinate Clause

The main difference between a relative clause and a subordinate clause lies in their beginnings and functions. Here is a comparison table highlighting their differences:

Feature Relative Clause Subordinate Clause
Begins with Relative pronoun (e.g., who, which, that) Subordinating conjunction or relative pronoun
Function Acts as an adjective, providing additional information about a noun or pronoun in the main clause Can act as a noun, adjective, or adverb, and cannot stand alone as a complete sentence

In summary, a relative clause is a type of subordinate clause that begins with a relative pronoun and acts as an adjective, while a subordinate clause is more general and can act as a noun, adjective, or adverb. A subordinate clause cannot stand alone as a complete sentence.
