Disinflation

What Does Disinflation Mean?
A slowing in the rate of price inflation. Disinflation is used to describe instances when the inflation rate has reduced marginally over the short term.  Although it is used to describe periods of slowing inflation, disinflation should not be confused with deflation.

Investopedia explains Disinflation
Disinflation is commonly used by the Federal Reserve to describe situations of slowing inflation. Instances of disinflation are not uncommon and are viewed as normal during healthy economic times. Although sometimes confused with deflation, disinflation is not considered to be as problematic because prices do not actually drop and disinflation does not usually signal the onset of a slowing economy.
