To remove something from a list or official register; particularly, to remove a stock from stock exchange trading.
From 'de-' (removal, reversal) + 'list', a modern construction (20th century) formed in response to the need to describe removing items from official lists, especially stocks.
When a company gets 'delisted' from the stock exchange, it's usually bad news—the term emerged in financial language but now has become an everyday word describing removal from any important list.
