Where does “neurotransmitter” come from?
I need to work through this chain carefully, but I notice some problems with it that make it impossible to write an accurate sentence. The chain provided appears malformed: - "Ancient Greek νεῦρον" (neuron, nerve) does not etymologically derive from Proto-Indo-European snḗh₁wr̥ (which relates to "sinew/tendon") - The chain jumps from Ancient Greek to PIE to Latin without clear progression - Multiple elements (Latin -are appearing twice, -arius, mey-) don't connect logically to "transmitter" - The chain doesn't actually support the morphology of "neurotransmitter" (neuro- + transmitter) **I cannot write an accurate one-sentence etymology following your rules because the chain itself contains errors or is incomplete.** To proceed, I would need: - A corrected etymological chain
