"The word transpiler is often used by people when they want to say that built a tool that transforms programs between languages of roughly the same level of abstraction."

Right off the bat, that sounds like a word with a commonly understood meaning.

Another meaning:

There are two classes of languages

* Interpreted, easy to learn, emphasize fast edit-debug cycles

* Compiled, harder to learn, more performant

Prototyping in python and rewriting in C++ or Rust is known as the "two language problem". Many of these efforts are trying to make the two language problem go away. Python -> Rust being the most in demand.

Note that both languages may be statically typed, functional etc.
