What is a "blunder" vs. a "mistake" vs. an "inaccuracy" vs. a "missed win"

I am new to this game and I really don't understand these terms. I would have thought missed win would mean a missed checkmate, but it doesn't. 

Blunder is big mistake, mistake is just mistake, inaccuracy is not as bad as mistake, and missed win means u missed checkmate

Oh man hard one but the pawn that the game said you should take will capture the bishop

If you search the help feature you are given this information:

Move descriptors: Each of your moves fall into one of these categories

Brilliant - This move not only was the best move but was difficult to find, even for the engine! Good job!
Best Move - The best move, according to the engine!
Excellent - A great move, but not quite the best!
Good - This move is okay, but could be better!
Book - An established opening move
Inaccuracy - This is a weak move that could be much better
Mistake - A bad move that immediately worsens your position
Blunder - A very bad move that could lose material or lose the game
Missed win - A move was missed that would have won material, or won the game

Thanks for the definitions (and I now realize what I was missing in the screenshot, so I took it down.
