Very good question with these words! :) In general, all of them are used to contrast something: 1) Despite the fact that she enjoys apples, she dislikes applesauce. 2) The woman had a fear of water most of her life; nonetheless, she quickly dove into the pool when her daughter was drowning. 3) She may, however, win the race after all. OR I did not sell that watch to her. However, she could have at least bought it at the store where I work. 4) The odds were against him to finish the race from the beginning. Nevertheless, he rose to the occasion and not only finished the race but won it as well. I hope the examples listed above show you when and where these words can be used. Remember, there is a bit more to them but this will start you off with a general overview. Message me if you'd like to get a more in-depth explanation. :)
