non-oil

The word is a modern English compound formed by directly combining the Latin-derived negative prefix 'non-' with the noun 'oil'. The prefix 'non-' originates from Latin 'non', an adverb meaning "not," which itself is a strengthened form of the Old Latin 'noenum', from 'ne-' (not) and 'oinom' (one). The base word 'oil' entered English via Anglo-French and Old French 'oile', from Latin 'oleum' (olive oil), which derived from Greek 'elaion' (olive oil), from 'elaia' (olive tree). The compound 'non-oil' logically constructs its meaning by directly negating the base noun, creating a term used primarily in economic and industrial contexts to specify sectors, revenues, or activities excluding those related to petroleum.
