Finding the right words can be a challenge, especially when it comes to technical language. The term "nonupdating discriminator" can be hard to understand for non-experts. Luckily, there are several synonyms that can make the meaning clearer. Want to convey the sense of something that remains unchanged? Try "static discriminator." Looking for a term that conveys the idea of an unchanging property that sets something apart? "Fixed discriminator" may be the way to go. Alternatively, using "constant discriminator" highlights the idea of a steady, never-changing attribute that doesn't need updating. No matter which synonym is used, it's important to use language that's clear and easy to understand by everyone.
