Synonym discussion

Sense: noun/1

Inflation describes a general, economy-wide rise in prices that reduces the buying power of money. Deflation is the opposite — a sustained drop in prices that can slow economic activity. Hyperinflation is an extreme and very rapid form of inflation where prices spiral out of control, often destroying a currency's value. Disinflation is different again: it means the rate of inflation is slowing down, but prices are still rising, just more slowly. The term cost of living is narrower than inflation: it tracks the price of essential goods and services such as housing, food, and healthcare, and can rise even when official inflation figures remain low. For example, a central bank might describe high inflation as 'a threat to long-term economic stability', while a household budget survey might warn about 'the rising cost of living for working families.'

Etymology

LatinFrenchEnglish

The word inflation comes from Latin inflatus, meaning 'blown into', the past participle of inflare (in- 'into' + flare 'to blow'). It originally referred to the physical act of filling something with air. By the 19th century, it had developed an economic meaning — a rise in prices caused by an increase in the supply of money and credit. The metaphorical sense of exaggeration emerged in the early 20th century.
