Morphology

absolute + alcohol

The adjective 'absolute' (complete, without addition) combined with 'alcohol' naturally signals 'pure alcohol', so a B1 learner who knows both words can infer it refers to alcohol lacking water. The precise technical threshold (≤1% water) is specialized, but the basic meaning of 'pure alcohol' is compositionally transparent and cross-linguistically common.

Etymology

Absolute alcohol gets its name from the old use of absolute to mean 'complete' or 'without water'. So, chemists called alcohol with no water 'absolute alcohol' to show it was 'without water', and today the phrase means alcohol that is almost completely pure.
