If you are someone who still loves the old joke: "Your epidermis is showing," natation is a word for you. It means floating but sounds like a terrible disease.
If you want to get really fancy, use this word in its two adjective forms: invite friends to swim in your pool by suggesting a "natatorial adventure"? Or refer to your bathing suit as "natatory attire." Although it sounds academic, natation is the simple act of flotation.
