inflation.
“Almost everyone uses the word inflation to refer to any increase in prices, but it ought to be reserved for a just one kind of price increase. True inflation has a different cause—and a different cure—than the price increases of goods and services caused by constantly changing supply and demand conditions.”
“Inflation is one of the most misused words in economics. As economist Michael Bryan carefully explained a few years back, the word originally described currency and money, not prices. It referred to a rise in the amount of paper currency in circulation relative to the precious metal (or money) that backed it. Later, the term referred to the amount of money in circulation relative to the amount actually needed for trade. Today, however, people typically use the word to refer a rise in some set of prices or even in a single price, with no necessary connection to money at all. So now we have countless types of inflation: oil-price inflation, healthcare inflation, wage inflation. The unfortunate outcome of this evolution is that the public no longer distinguishes between two very different types of price pressure.
Strictly speaking, inflation refers only to a drop in the purchasing power of money that results when a central bank creates more money than its public wants to hold.“
