Isaiah

The origin of Isaiah is debated, and we couldn't confirm its meaning from a sourced etymology. A commonly cited theory links it to Hebrew roots, with the meaning “God is salvation”. Treat that as a theory, not a settled fact.

Why we say this: we only state a meaning as fact when a sourced etymology (Wiktionary, with its references) supports it. For Isaiah we didn't find one we were confident in, so we show the popular explanation as a theory.
