Morphology

lethal + dose

The meaning 'the amount of a substance sufficient to cause death' is directly and transparently derived from combining 'lethal' (causing death) with 'dose' (a measured amount of a drug). This simple adjectival+noun composition is common and cross-linguistically shared, so a B1 learner who knows both constituents will readily infer the MWE meaning.

Etymology

The phrase lethal dose comes from a simple picture: a certain dose, an amount of a drug or chemical, is lethal, meaning able 'to kill'. So, lethal dose means the amount that will cause death.
