Do you ever realize you just made up a word when there is already a word for what you mean? Here is an example... someone I know recently made up the word comfortability, when comfort would have been the correct word to use. It was used something like this, "I like the way that one looks, but I think comfortability-wise, this one is a better choice."
You get what I'm sayin'. So, Gavin and I are in the bathtub, having a splashingly fun time pouring water from one cup into another, spraying water all over the wall and the floor, kicking legs, etc. At the end of the bath, I usually give him a little 'swimming lesson'. Meaning, I lay him on his back in the water and I hold his head and neck with both hands and I let him float. He loves it. I want him to like the water, to love to be in it, to not be afraid to swim. So, this is my way of getting him to like floating and not be afraid that he might sink. He floats really well. He naturally floats. He has no problem with sinking...
So, I say, "Wow, Gavin. You're really _________."
You're really floatacious! I meant buoyant, obviously. But I kind of like floatacious... it's a bodacious word! Not like comfortability.
