While the words "common" and "ordinary" might seem interchangeable, there are subtle yet important differences between them. "Common" typically refers to something that happens frequently or is widespread, while "ordinary" suggests something is typical, unexceptional, or even a bit boring. Think of "common" as relating to frequency and "ordinary" as relating to a lack of distinction.

Let's look at some examples to illustrate the difference:

• Common: "Colds are a common illness." (Meaning: Colds are frequent.) Translation: (Same meaning)

• Ordinary: "It was an ordinary day at school." (Meaning: The day at school was typical and uneventful.) Translation: (Same meaning)

• Common: "That's a common misconception." (Meaning: Many people have this wrong idea.) Translation: (Same meaning)

• Ordinary: "He led an ordinary life." (Meaning: His life was unremarkable.) Translation: (Same meaning)

• Common: "Apples and bananas are common fruits." (Meaning: These fruits are frequently seen.) Translation: (Same meaning)

• Ordinary: "She wore an ordinary dress." (Meaning: Her dress was not special or unique.) Translation: (Same meaning)

Notice how "common" emphasizes frequency or prevalence, whereas "ordinary" highlights the lack of anything special or outstanding. Sometimes, you can use them interchangeably, but paying attention to these nuances will make your English sound more precise and natural.
