'This is a transpiler' gives me a massive amount of additional context compared to 'this is a compiler' - likely structure, implementation techniques, output. Not all transpilers will fit this usual structure, but if they do you can tell me by changing this one little word. Powerful communication tool, I think.
But neither 'this is a transpiler' or 'this is a compiler' provide any meaningful information without specifying the compatible inputs and outputs. Once the inputs and outputs are specified then it is already reasonably known if the operation is transpilation or compilation, making the distinction between transpiler and compiler redundant.
