Morphology

linearity = linear (transparent) = line + ar + ity

Standard noun formation from the adjective 'linear' using the productive suffix '-ity' to indicate a state or quality.

Etymology

Linearity comes from linear, from the Latin linea meaning 'line'. Imagine points on a graph that fall on a single straight line, and you can see why linearity means a direct, straight-line relationship between two things.
