They are: froth, muddle, repatriate, and exuberant.
Froth means bubbles. Mass of bubbles. Usually created by a melange of warm water and soap in a bath tub. Can also be found on top of a beer in a glass. Frothing can be considered as a verb, similar as bubbling. But frothing works in a sweeping manner. Consider while walking near a beach, where sea would sweep you endlessly. You can say the sea froths you as well, as bubbles are usually formed as a result of it.
Muddle can mean a lot of things. It can be used to represent a state of confusion. Or if combined with through, as in muddle through, can represent the meaning of battling through and succeed. He muddles through the players to get a touchdown. Everything is in a muddle, we need to fix this mess now!
Repatriate means send something back to its origin. French gov seeks to repatriate thousands of Algerian refugees. As you can see, you don't need to mention "back" or where to. Though you can I believe. A repatriate is a person that is sent back home to his or her original place.
Exuberant. Overwhelming! Plentiful! Overflowing! It just shows. The excitement, the energetic radiance. It's bouncy! In fact, this paragraph is littered with exclamation marks to describe the meaning of the word exuberance itself! Exuberant crowd, exuberant cheerfulness, exude exuberance (excitement etc.). The grapes plant has grown exuberantly, covering the six feet fence in just one week!
