The term 'committee head' is used to refer to the leader of a committee. This person is responsible for overseeing the activities of the committee and ensuring that its goals are met. The two most common terms used to describe this role are 'CHAIR' and 'CHAIRPERSON'. The former is a five-letter word, while the latter is an eleven-letter word. The CHAIRPERSON is typically the one who presides over meetings and is the public face of the committee. They are also responsible for setting agendas, delegating tasks, and making sure that the committee is running smoothly.
