Morphology

neurotransmitter = transmitter (semi-transparent) = neuro + transmit + er

The meaning is understandable from 'neuro-' plus 'transmitter', but the term is a specialized scientific label rather than a fully everyday combination.

Etymology

The word neurotransmitter combines neuro- ('nerve') and transmit ('to send across'), like when you 'transmit' a message. So a neurotransmitter is a chemical that sends signals from one nerve cell to the next across a small gap.
