#i know part of it probably is bc it's rare to use “óleo” when referring to cooking oil. it's mostly only used when referring to oil paint

Something I find mildly imteresting about my language is that the universally agreed upon term for "olive oil" is "aceite de oliva", because like

Spanish has two words for "oil", one comes from latin ("óleo") and the other comes from arabic ("aceite"). Similarly, we have two words for "olive", from latin we get "oliva" and from arabic we get "aceituna".

So at some point we decided that the correct way to form the phrase "olive oil" is to use the arabic root for the oil and the latin root for the fruit.
