Dominance means having power or control over others, or being the strongest or most important in a group or situation. When one team shows dominance in a basketball game, they control the action and stay ahead the whole time. When a single company achieves dominance in an industry, it becomes far more successful and influential than its competitors.

In nature, biologists observe dominance when studying animal groups. A dominant wolf in a pack gets to eat first and influences decisions about where the pack goes. A dominant tree in a forest grows tallest, spreading its branches wide and capturing the most sunlight while smaller trees struggle in its shade.

Dominance isn't the same as leadership, though they can overlap. A good leader might be dominant because others trust and follow them. But someone can be dominant simply through greater strength, size, or resources, without necessarily being a good leader at all. In sports, a team's dominance comes from superior skill and preparation. In a classroom discussion, one student's ideas might achieve dominance because they're the most convincing, not because that student talks the loudest.

The word appears frequently when people analyze competition, whether in business, sports, politics, or nature. Understanding dominance helps explain why some individuals, groups, or ideas become more powerful and influential than others.
