I'm working on a dictionary which can translate words between two languages. It can however also "translate" between the same language, which means that it finds a synonym.
In this context the definition of "synonym" according to Merriam-Webster is:
1 : one of two or more words or expressions of the same language that have the same or nearly the same meaning in some or all senses
The definition of "translation" in this context according to Merriam-Webster is:
1 : an act, process, or instance of translating: as a : a rendering from one language into another; also : the product of such a rendering
This means that both words are directly conflicting. I am looking for a word that can mean both.
