secondary

Secondary refers to something that is not primary or first in importance, order, or rank. It can be used in various contexts, including mathematics, education, and everyday language.

In mathematics, the term "secondary" often refers to a secondary quantity or variable, which is derived from or dependent on primary quantities or variables. For example, in physics, velocity is a secondary quantity derived from position and time.

In education, secondary education typically refers to the phase of education that follows primary education. It usually begins after the completion of elementary school and continues until the end of high school or secondary school. Secondary education often includes subjects such as mathematics, science, social studies, and languages.

In everyday language, "secondary" can describe something that is less important or less central to a situation. For example, a secondary effect is a consequence that is not the main or primary result of an action or event.

The term "secondary" is often used in contrast to "primary," which refers to something that is first in importance, order, or rank. For example, a secondary color is a color that is made by mixing two primary colors.
