Obviously both "sides" believe their definition of inflation is the right one but it always leads to confusion and/or fights. If everyone simply used the terms price inflation or money supply inflation it would always be clear.
There was only one definition before the Federal reserve was brought in 1913 and after that two definitions began with the monetary base obviously expanding in a simple relationship and so effecting prices and the government defined idea of inflation adjusted for various policies and ideas.
Especially now with an unfixed worth to dollars, inflation is a variable description where as the original idea of reference to a known quality is the same as ever. Seems like a reinvented word to me, you can take the spoken meaning slang or the original definition.
Currently monetary base inflation is very high, much higher then GDP or population growth but the government inflation figure is very low. The reason that matters is that inflation exceeds interest rates, debt repayment rates by government and companies and it exceeds the rates wages increase every year. Inflation exceeds GDP growth which if correct would trigger the word recession and this is not an acceptable conclusion taught in current economics. I think its very political and we view the world through a goldfish bowl to gain a certain perspective, large debt is valued over production. Governments have large debts, unserviceable otherwise so every party agrees with this current view
