That's a really good question! I think it'll be helpful to other people as well.
First, I'll recommend two methods!
*The first is 'know the real meaning'.
You can read the meanings and examples of words written by native speakers through Google's English dictionary. I'll write down the method below.
1) Search 'words + mining' on Google ex) obssess mining
2) Scroll down and click on 'Cambridge Dictionary' at the top (link:
https://dictionary.cambridge.org/ko/%EC%82%AC%EC%A0%84/%EC%98%81%EC%96%B4/obsess)
*The second is 'Listen to native speakers use this expression in their daily lives.'
I'll write down the method below.
1) Search the word 'obsess' on YouTube
2) Click on the various videos that include "obsess" as the title, and listen directly to whether they are used as an understanding in Google's English dictionary.
In addition to the dictionary meaning, the best way to know what kind of situation a native speaker uses the word in conversation is to listen! :)
