Explanation

A leader is the one in the charge, the person who convinces other people to follow. A great leader inspires confidence in other people and moves them to action. A leader is the head guy or gal, the one running the show. The leader of the band calls the shots and sets the tempo for the music. A conductor is the leader of an orchestra; all musicians look to him or her to know when to begin and end playing their instruments. A president is the leader of a country whose decisions make a difference to the whole population. Martin Luther King, Jr. was a leader of the Civil Rights Movement. A leader comes first in line — in a parade or a social system — and gets a lot of attention, but ultimately, a leader needs followers.
