Linearist

Linearist is a term that does not have a single, universally accepted definition across disciplines. In general, it refers to a person who studies, favors, or applies linear concepts—such as linear relationships, linear models, or linear structures—rather than nonlinear ones. Because it is not a standardized title, usage is often informal and context-dependent.

In mathematics and related fields, a linearist is someone who works with linear algebra, linear transformations, and linear spaces, or who develops and tests methods that rely on linearity. This may include the study of systems of linear equations, superposition principles, and additive models in statistics. In practice, the term is rarely used as an official designation, and more precise terms like mathematician, statistician, or analyst are preferred.

In applied domains such as engineering, economics, or data analysis, "linearist" may appear as a casual descriptor for practitioners who employ linear methods or approximations, such as linear control design, linear regression, or linear programming. The label is not standard in these fields, and professionals typically identify themselves by their specific methods or specialties.

Etymology and usage notes: The word derives from Latin linearis "of a line" and the suffix "-ist" indicating a practitioner. Because "linearist" is uncommon, it may be vague or confusing without context. When precision matters, it is better to specify the field and the exact focus (for example, linear-algebra specialist, regression analyst).
