Difference Between Fear and Fright

Question

I learn that as a noun fright is a derivative of fear. What's the difference between these two? I read that fright is more intense than fear, is it true?

I also read the explanation here, but I can't quite understand the difference in the usage.

Answer 1

Fear may be an ongoing state resulting from living in dangerous times or knowing that your future is particularly uncertain.

If something gives you a fright, it is a sudden perception of immediate threat, such as thinking you hear an intruder in the night.
