Answer 1

threshold is the piece over the ground that your door fits into (metal or wood, generally).

Or, when you have reached your threshold of pain, for example, that's as much pain as you can handle before you need medication, or die, or whatever...

Go to an online encyclopedia, wikipedia.org.  You can search for definitions in there and get insight from people that post to it, as well. It's helped me a lot.  Good luck!
