Q.Define economics according to Adam Smith.

Adam Smith, writing in 1776, looked at economics primarily as the study of how nations grow prosperous.

Adam Smith is regarded as the founder of modern economics because of his 1776 book An Inquiry into the Nature and Causes of the Wealth of Nations. In it, Smith examined why some nations become wealthy while others remain poor, focusing on the division of labour, free trade, and the accumulation of capital as the key drivers of a nation's wealth. On this basis, Smith's definition treats economics as a science concerned with wealth: its production (how goods and services are created), its accumulation (how nations build up capital over time), and its distribution (how the resulting income is shared among landlords, workers and capitalists). Because this definition places wealth — rather than human welfare — at the very centre of the subject, later economists such as Ruskin and Carlyle criticised it as a 'gospel of mammon,' arguing it reduced human beings to mere wealth-seekers. Even so, Smith's wealth definition remains historically important as the starting point from which every later definition of economics reacted.
