Morphology

noradrenaline = adrenaline (semi-transparent) = nor + adrenal + ine

The word is clearly formed from 'adrenaline', but the prefix 'nor-' is a specialized chemical combining form whose precise meaning (a demethylated derivative) is technical and not obvious to general learners.

Etymology

Noradrenaline is made from the beginning nor- and adrenaline. In chemistry nor- often means 'without' or 'missing a small part', so noradrenaline is a close relative of adrenaline and, like it, is a hormone and brain signal that helps the body get ready for stress.
