The meta answer is the five-letter word that should go in the missing ???? of the grid. It's up to you to figure out whether this grid is missing its top row, right column, bottom row, or left column, as well as what word should go there.
If anyone is wondering about the title, I choose the answer and position (left, right, top, bottom) for these metas via random word and number generators, and I found it ironic that FLOAT is sinking in this puzzle. Just luck of the draw that it wound up in the bottom row.
