“Inflation” doesn’t mean anything by itself. It is a shorthand for either price inflation or monetary inflation. Or inflating a balloon. Context is needed.
It absolutely does when the correct definition is still used. Inflation is an increase in money supply, that's really all there is to it.
Your point is why the use of "inflation" to mean price increases is so meaningless. Prices change for any number of reasons and you need context. When "inflation" still means in increase in the money supply there is no context required to know what it means, though obviously that's not all the information you need to understand the economy.
You are wrong and that's why you are misunderstood.
I would suggest just saying "increase in money supply" if you mean increase of money supply instead of using a term that means "a continuing rise in the general price level". That will make people understand what you mean.
