“Other than” does not mean “different from every imaginable sense.” It means different from the assigned sense relevant to the discourse. Where ordinary linguistic meaning and an established technical meaning differ, context identifies which convention is operative.
The issue is not simply what meanings a dictionary lists historically, but which assignment governs this conversation. Without that determination, a conventional technical usage may be wrongly labeled figurative.
This guards against arbitrary classification, but the conversational context must not be stretched so far that every speaker’s intended meaning becomes a new convention. That would erase the stable distinction between literal and figurative use.
