Etymology
Etymology Information

'nonfossil' originates from English, specifically from the prefix 'non-' + the word 'fossil', where 'non-' meant 'not' and 'fossil' ultimately comes from Latin 'fossilis' meaning 'dug up'.

Historical Evolution

'fossil' entered English via Medieval Latin 'fossilis' and Old French 'fossile'; the English negative prefix 'non-' has been productively attached to nouns and adjectives in modern usage, producing the compound 'nonfossil' in technical and policy contexts.

Meaning Changes

Initially, 'fossil' referred to something 'dug up' from the ground; over time it came to denote remains or fuels formed from ancient organic matter ('fossil fuels'), and 'nonfossil' developed to mean 'not derived from fossil fuels' in energy-related usage.
