Meaning of “BUT” – Core Definition
BUT is a coordinating conjunction. In English, it joins two independent clauses together, signaling a relationship such as contrast, addition, cause‑effect, or surprise. While the word AND primarily indicates addition, BUT introduces a shift from one idea to another, often highlighting an unexpected twist.
Example: “She finished her homework but she didn’t get enough sleep.” Here, BUT shows the opposite outcome despite completing the task.
Understanding that BUT acts as a bridge between ideas makes it easier to spot its proper use and to avoid misplaced commas.
