While both "detect" and "discover" involve finding something, there's a key difference. We use "detect" when we find something that is often hidden or not easily noticeable, usually using special tools or skills. Think of it as finding something that was there all along, but we needed specific methods to find it. On the other hand, we use "discover" when we find something new or previously unknown to us. It often implies exploration and a sense of excitement. The discovery might be something entirely new to the world, or just new to us personally.

Here are some example sentences to illustrate the difference:

• Detect:

  • "The doctor detected a small tumor during the scan." (English translation: The doctor found a small tumor during the scan.)
  • "The smoke alarm detected smoke and alerted the family." (English translation: The smoke alarm found smoke and warned the family.)

• Discover:

  • "Scientists have discovered a new species of plant in the Amazon rainforest." (English translation: Scientists have found a new type of plant in the Amazon rainforest.)
  • "I discovered a hidden path through the woods." (English translation: I found a secret path through the woods.)

Notice how "detect" often involves a process of searching for something specific, while "discover" implies finding something unexpectedly or something new and previously unknown. The object of "detect" is often something that is hidden or needs special skills to be found. The object of "discover" is something that was previously unknown.
