    That definition is literally describing a change, as rate of change.

    Inflation is a loss of purchasing power

    Over the past year, we haven’t experienced a loss of purchasing power. We have a lack of purchasing power, but we lost it over the 2-3 years prior to the last year.

    a rise in prices for goods and services over time

    This is pretty much the mathematical definition of a rate of change. Like how speed is the rate of change in position over time. After a day of traveling, your position (prices for goods) may be way different than your starting point, but if you’re not currently moving, your speed (inflation) is NIL.
