The word 'incumbent' is often used in politics to refer to a person who currently holds an official position or office. For example, if someone is the current president, they are the incumbent president. The word can also be used in a more general context to refer to something that is currently necessary or required. For instance, if a company has always used a certain software program, it might be referred to as the incumbent software even if other programs are available.
