Share means - "Part" and in the language of the stock market "Share" means - "Part in companies". When you buy shares of a company, you become a company shareholder. For example, if a company has issued a total of 1 lakh shares and you have bought 10,000 shares out of it, then you become a 10% shareholder of that company. You can sell these shares in the stock market whenever you want.
