Morphology

Einstein's + theory + of + relativity

The phrase is fully compositional: 'Einstein's' indicates authorship/association, 'theory' denotes a set of scientific ideas, and 'relativity' names the specific concept. A B1 learner who knows these constituents can readily infer it refers to the scientific theory about relativity associated with Einstein; the possession + noun pattern is common cross-linguistically, so the meaning is predictable.

Etymology

Einstein's theory of relativity comes from Albert Einstein's idea that the way we measure 'space' and 'time' changes when we move fast. Imagine two clocks, one on a fast train that runs slower and one on the ground that runs faster; that's why the word relativity means 'not the same for everyone' and why the theory shows measurements depend on who is watching.
