What's the difference between "chief" and "captain"?
Answer from a Native speaker
"Chief" and "captain" are both high-ranking officials/leaders. A "chief" is usually a leader of a group or a clan, such as chief of police or chief of a tribe. A "captain" is usually a leader in the military or commander of a ship. Ex: Sitting Bull was a famous Native American chief of the Teton Sioux tribe. Ex: Captain Phillips is a movie based on a true story of a ship hijacking by Somali Pirates and how Captain Phillips survived it.
