📚 What is a Noun Clause?
A noun clause is a group of words that contains a subject and a verb, and acts as a noun. It can function as a subject, object, complement, or appositive within a sentence.

🔍 Subject: What he said surprised everyone.
  🎁 Direct Object: I don't know what I should do.
  💬 Predicate Nominative: The problem is that he doesn't listen.
  📌 Appositive: The rumor that she is leaving is false.

📖 What is an Adjective Clause?
An adjective clause, also known as a relative clause, is a group of words that contains a subject and a verb, and modifies a noun or pronoun. It usually begins with a relative pronoun (who, whom, which, that) or a relative adverb (where, when, why).

👩‍⚕️ The doctor who treated me was very kind.
  🏡 The house where I grew up is still there.
  🗓️ The day when we met was unforgettable.

💡 Key Takeaways

🔑 Function is Key: Noun clauses act as nouns, while adjective clauses modify nouns.
  🧐 Introductory Words: Pay attention to the words that introduce the clause. Different words often signal different types of clauses.
  📝 Replaceability: Try replacing the clause with "it" or "something." If it works, it's likely a noun clause.
  ✂️ Essential vs. Non-essential: Adjective clauses can be essential or non-essential, affecting whether commas are needed. Non-essential clauses add extra information.
