Morphology
The name 'lead arsenate' is transparently compositional: it combines the metal 'lead' with the anion 'arsenate', so a learner who knows both constituents can infer it is a chemical compound made of lead and arsenic. This follows regular chemical naming patterns (metal + oxyanion) that are predictable across languages, so the core meaning is derivable even if specific details (formula, toxicity, historical use) require extra knowledge.
Etymology
Lead arsenate is made from two words: lead and arsenate, with arsenate coming from the poisonous element arsenic. Farmers once dusted fruit trees with this white powder to kill insects, so the name today refers to that 'poisonous' insecticide.
