Which sentence uses a semicolon correctly?

I love to read; it's one of my favorite hobbies.

To determine which sentence uses a semicolon correctly, we need to understand the proper usage of semicolons. A semicolon is used to connect two independent clauses that are closely related but could stand alone as separate sentences.

Let's look at a few examples:

1. I enjoy hiking; it allows me to connect with nature.
2. She loves to read books; especially mystery novels.
3. The concert was canceled; due to bad weather.

In these examples, all three sentences use semicolons correctly. Each semicolon connects two independent clauses that could be separate sentences.

Sentence 1: "I enjoy hiking" and "it allows me to connect with nature" are two independent clauses, closely related and properly connected with a semicolon.

Sentence 2: "She loves to read books" and "especially mystery novels" are two independent clauses, closely related and properly connected with a semicolon.

Sentence 3: "The concert was canceled" and "due to bad weather" are two independent clauses, closely related and properly connected with a semicolon.

Therefore, all three sentences use semicolons correctly.

The sentence "I have a big test tomorrow; I need to study all night" uses a semicolon correctly.
