Surface Forms
Morphology
nitrogen = nitro (opaque) = nitro + gen
Although formed from the combining form 'nitro' plus the suffix '-gen', the meaning 'the gaseous chemical element that makes up most of the air' is not deducible by an average B1 learner from these parts alone.
Etymology
Nitrogen comes from two parts: nitro-, from a word meaning 'saltpetre', a natural salt, and -gen, meaning 'to make' or 'to produce', as in generate. Scientists named the element this because they first found it in saltpetre compounds, so nitrogen is now the name of the gas that fills most of the air and that plants need to grow.
