=neurotransmitter
neuro- (nerve) + transmitter (a thing that sends) = 'a nerve-signal sender.' The chemical messenger that ferries a signal across the gap (synapse) from one neuron to the next. The 'transmitter' half traces to Latin trans- (across) + mittere (to send) — the same mit/miss root in transmit and mission.
