Morphology

lactic + acid

The noun is compositionally built from 'lactic' (pertaining to milk) + 'acid' so a learner who knows both constituents can infer it denotes an acid related to milk. While the full technical usage (e.g., produced in muscles during exercise) is domain-specific, the basic referent is directly derivable from the parts.

Etymology

Lactic acid The word lactic comes from an old word for 'milk' because this acid was first found in sour milk and yogurt. So the name helps you remember that lactic acid is the acid in dairy and the same acid that can build up in muscles after hard exercise.
