Converting a programming language to another form, while maintaining the execution semantics is “translating” or “compiling”.
For example: The first C++ implementation (cfront circa 1983) was called a “translator” because it translated C++ into C.
There is no need for a new word — we’ve been translating and compiling for more than 60 years.
Boycott “transpiler” — “translator” is enough.
