⏰ Warm-up (5 mins)

Activity: Review independent and dependent clauses. Write down three independent clauses and three dependent clauses.

🖋️ Main Instruction

➡️ Connecting Independent Clauses

A semicolon can join two related independent clauses (clauses that could stand alone as sentences) without a coordinating conjunction (and, but, or, nor, for, so, yet).

Example: The rain poured down; the game was canceled.

• 💡 Tip: Ensure the clauses are closely related in meaning.

➡️ Using with Conjunctive Adverbs

A semicolon is used before a conjunctive adverb (e.g., however, therefore, moreover, furthermore) when it connects two independent clauses. A comma follows the conjunctive adverb.

Example: I wanted to go to the park; however, it started to rain.

• 📝 Note: Common conjunctive adverbs include: however, therefore, moreover, consequently, nevertheless, subsequently, accordingly, also, besides, still, thus.

➡️ Separating Items in a Complex List

When items in a list already contain commas, semicolons can be used to separate the items for clarity.

Example: I have lived in Seattle, Washington; Paris, France; and Rome, Italy.

• 🧭 Guidance: This usage prevents confusion when list items themselves contain commas.

common errors to avoid

• ❌ Incorrectly joining an independent clause with a dependent clause.
• ⚠️ Overusing semicolons; use them judiciously for clarity and flow.
• ✍️ Forgetting the comma after a conjunctive adverb.
