Morphology

lethal = leth + al

The segment 'leth' is not a productive English base word and the adjective is formed with a Latin-derived suffix '-al', so learners cannot derive the meaning from a familiar English base like 'death'.

Etymology

Lethal comes from the Latin word letum, which means 'death'. So something called lethal can cause death, which is why we use it for deadly weapons or poisons.
