Where does neuronal come from?

Language of origin: Greek

This word is built on neuron, which English took directly from the Greek neuron, a word that originally meant 'sinew', 'tendon', or 'cord' rather than a nerve cell. In ancient anatomy the line between sinews, ligaments, and nerves was blurred, so the same term covered any tough fibrous strand, and the sense of a thread carrying signals only sharpened much later. The modern scientific 'neuron', meaning a nerve cell, was popularised in the 1890s when researchers such as Wilhelm Waldeyer named the basic units of the nervous system. The adjective neuronal then formed by adding the Latin-derived ending -al, which turns a noun into a describing word, giving the meaning 'relating to neurons'. The same Greek root survives in relatives like 'neurology' and 'neurotic', and the spelling trap lies in keeping the single -on- of neuron before adding -al, since writers sometimes drift toward 'neural' or double letters that do not belong.

How the word is built
