Morphology

sublinear = linear (transparent) = sub + linear + inear

The adjective is directly formed by the productive prefix 'sub-' plus the adjective 'linear', yielding the compositional meaning 'less than linear' or 'below linear rate'.

Etymology

Sublinear starts with sub- meaning 'under' or 'less than' and ends with linear, from line meaning 'straight line'. So sublinear describes growth or running time that goes up but stays below a straight line, meaning it increases more slowly than a linear rate, which is why people use it in math and computer work.
