A language can be designed once and then interpreters and compilers (and transpilers) can be made available for it.
Python is a classic example: it's most commonly interpreted, but can be compiled when performance matters.
C is usually compiled, but tcc offers the option to directly run it from source (-run).
History has given us both compilers and interpreters for various dialects of BASIC since the 80s.
Honestly I can't imagine why a language designer should decide upfront if the result of their study will be interpreted or compiled. And I have no idea what choices should they make to characterize it as a "scripting" language.
