oil-spill

The compound noun 'oil-spill' is a modern formation directly describing an environmental incident. The first element, 'oil', traces back through Latin and Greek to the ancient Mediterranean world, where it specifically meant olive oil, a precious liquid. The second element, 'spill', has a more violent Old English and Norse origin meaning to destroy or kill, which semantically softened to mean a wasteful or accidental pouring out. Combined in the 20th century, the term logically constructs the meaning: the destructive or wasteful release of oil, reflecting the environmental hazard it names.

Structure: oil (liquid fuel) + spill (accidental release) - oil: From Old French 'oile', from Latin 'oleum' (olive oil, oil), from Greek 'elaion' (olive oil). Functions as the substance noun. - spill: From Old English 'spillan' (to destroy, kill, waste) and related to Old Norse 'spilla' (to destroy). Its modern sense of accidental release or overflow developed later. Functions as the event/action noun.
