Morphology

lethal + agent

The meaning is directly compositional: 'lethal' means causing death and 'agent' denotes the thing or substance causing an effect, so a learner who knows both words can infer 'a substance or factor capable of causing death.' This follows regular noun-modifier patterns and has clear parallels in other languages (e.g., Spanish 'agente letal'), supporting immediate comprehension.

Etymology

Lethal agent combines lethal, meaning 'causing death', and agent, meaning a 'thing that does something'. So imagine a dangerous bottle, gas, or force that acts to kill, and that's why the term means 'a substance or factor capable of causing death'.
