What does primary mean?
Primary means first in importance, rank, or sequence. It is used for something that functions as the main example, concern, or stage in a larger system: a primary aim, a primary cause, or a primary school. The word often suggests both precedence and foundational importance, so a primary responsibility may be both a central duty and a duty that comes before later tasks. In political contexts, especially in the United States, a primary is a preliminary contest in which voters choose candidates for a subsequent election. The related adverb primarily means mainly or for the most part, while primacy refers to the state of being first or most important. Because primary comes from a Latin word meaning “first,” it is especially useful when describing something that belongs to the beginning, foundation, or chief level of a process.
Chief or principal in importance; first or earliest in a sequence or system.
"The team made improving reliability its primary priority."
When referring to an early stage of education or development, primary often contrasts with secondary.
A preliminary election in which candidates are selected to run in a later election.
"Several senators contested the state primary."
The noun is especially common in American political usage; in Britain, “primary election” is also used, though “general election” is the more usual term for the final national contest.
The plural refers to multiple preliminary elections or selection contests, often held at different times or in different places.
"The candidates won primaries in several states."
From the Latin for “first,” primary has always pointed to what comes first in importance or order.

Where does primary come from?
The adjective and noun derive ultimately from Latin primarius, meaning “of or belonging to the first,” which was formed from primus, “first.” English borrowed the word in the late 16th century, initially in contexts involving first place or earlier stages. Its development led to modern uses relating to main importance, elementary education, and preliminary elections.
