"Sell on" is a phrase commonly used in business and commerce. It means to sell something that was previously purchased, usually for a profit. For example, if a store buys a product from a manufacturer and then sells it to a customer for a higher price, they are selling on the product. You can also use "sell on" in a more abstract sense. For instance, if someone is persuading others to support a certain idea or belief, they may be trying to "sell on" their own viewpoint. In short, "sell on" refers to the act of selling something that was previously bought or promoting an idea or belief to others.
