A group leader is a person who is responsible for managing and leading a group of people. The term can be broken down into three words: KINGPIN (7 letters), GUIDE (5 letters), and HARDG (5 letters). KINGPIN refers to the leader of a group, someone who is in charge and has authority over the group. GUIDE is someone who provides direction and support to the group, helping them to stay on track and reach their goals. HARDG stands for Head of Administration, Research, Development, and Governance, which is a role that involves overseeing the operations of the group and ensuring that they are running smoothly.
