Morphology
The expression is compositionally built from 'world' (global) + 'war' (armed conflict) + 'one' (first), so a B1 learner who knows those constituents can infer it refers to the first global-scale war even without knowing specific dates or belligerents. The 'World War + ordinal' pattern is common cross-linguistically (e.g., Primera Guerra Mundial), which further supports immediate comprehensibility.
Etymology
World War 1 comes from a simple image: it was a war that pulled in many countries from around the world, and the number 1 shows it was the 'first' war on that scale. So today World War 1 means the big global conflict fought from 1914 to 1918.
