what is the difference between microeconomics and microfinance? what is the difference between microeconomics and microfinance?

I cannot understand the difference between the two terms
Kind of a good question, but it's to do with etymology, nitpicking or something. While economics is the allocation of scarce resources and finance is the allocation of scarce resources over time, microeconomics is a study while microfinance is a provision of financial services.

Thus, the 'micro' in microeconomics refers to the scope of study namely that microeconomics studies the behaviors of individuals and firms instead of state issues of growth, inflation, and unemployment.

However, the 'micro' in microfinance refers to the scope of recipients of financial services.
