Root Explanation

Noradrenaline is formed from "nor-" (meaning not or without) and "adrenaline" (from Latin "adrenal" meaning near the kidneys and "-ine" indicating a chemical substance). The word refers to a chemical substance that is similar to adrenaline but lacks a specific methyl group, hence the prefix 'nor-' indicating its modified state.

Memory Tip

Think of 'nor-' meaning 'without' and 'adrenaline' being a chemical related to the kidneys — noradrenaline is like adrenaline but without a certain part.
