English picked up dominant in the 16th century, first in legal and political senses, then expanding into science and everyday talk. You can trace related forms in Romance languages, where domin- roots often relate to ownership or command.

dominant definition appears in many ordinary phrases. People say a company is dominant when it controls a market. Musicians call a note or mode dominant when it has a strong pull toward resolution.
