Microeconomics is the study of the small pieces inside an economy: a household deciding how to spend, a firm deciding what to make, the price of one thing in one market. Typical questions are: why does this cost more? what happens if the government taxes this one product? The matching subject for the whole country is . Teachers split the two because it helps you start, though actually they leak into each other — trouble in one market can spread. People also say “the microeconomics of X” to mean the small-scale money facts of that one thing, even outside a classroom. It is a formal, classroom word. Grammar trick: it looks plural because of the -s, but it names one subject, like physics, so we say microeconomics is, not are. In Taiwan, school and university courses call this 個體經濟學. Micro- does not mean “”; it means “looking close up.”
個體經濟學（中國大陸教科書多作「微觀經濟學」）
組成micro- (small-scale) + economics. Economics comes, through Latin oeconomia, from Greek oikonomía: oîkos “house” + nómos, from a verb némō “to manage / to deal out.” The old picture is managing a household; later it grew to mean managing money and markets. The micro- says: look at one household, one firm, or one market, not the whole country.
