The modern meaning of "inflation" is newspeak. You pointed out that "cash" is newspeak. I had never heard of the definition you referenced in your dictionary until I started reading and watching Bitcoin related content. I always thought it was strange they would use some other definition. Doesn't doing so only confuse the uninitiated?

There are large communities that see inflation meaning one thing and another that sees it means the other. I use the phrase "money supply expansion" so others can understand. I have found distinct meanings for "technical analysis" and also "money".
