Đâu là sự khác biệt giữa complex và involved và complicated ?Hãy thoải mái đưa ra các câu ví dụ nhé.

我覺得你知道這些意思是相似的 🙂
Based on usage, "complicated" is used more often, followed by "complex", then "involved".

Again based on usage , "complicated" if often used in simple everyday conversations.
"Complex", you'll hear this more on technical topics.

"Involved", I rarely hear or use this for this definition, because of its other meaning which is "to take part in" or "be a part of something", like: "She is involved in the project."

examples:
"His relationship is complicated."
"The parts of the machines is complex. You cannot easily manipulate it."
"The plot of the movie is long and involved. It's difficult to explain if you haven't watched it."

If you have Line, you can ask more questions on this there. 🙂
