Where does “cocaine” come from?

I appreciate the detailed instructions, but I need to flag a significant issue with the etymology chain provided: it doesn't actually support the word "cocaine." The chain you've given traces "coca" back through various language stages, but "cocaine" is a derived form created in English (and other languages) by adding the chemical suffix "-ine" to "coca" in the 19th century. The chain provided doesn't account for this modern word formation step, and the intermediate steps listed (multiple "Latin -inus" entries, Proto-Indo-European roots) don't clearly connect to either "coca" or "cocaine." To write an accurate one-sentence etymology following your rules, I would need a chain that either: 1. Properly traces "cocaine" (including when and how the "-ine" suffix was added), or 2. Traces "coca" (the base word) with a note about the suffix Could you verify the etymology
