Morphology

order + of + magnitude

A learner who knows 'order' (degree/level) and 'magnitude' (size/extent) can plausibly infer that 'order of magnitude' refers to a level or class of size, so the basic compositional sense is accessible. However, the conventional quantitative meaning (specifically steps of ten / a logarithmic scale) is technical and not fully predictable from the parts, so prior exposure or domain knowledge is usually required.

Etymology

Order of magnitude comes from a simple number idea used to compare very different sizes. The words order and magnitude show a picture of steps: each order is about 'ten times' bigger than the one before, so the phrase means a rough 'level' of size or amount.
