Another example where the tree diagram is incorrect: https://www.google.com/search?q=etymology+oligarchy https://www.google.com/search?q=etymology+oligarchy The current tree diagram makes it look like the Greek oligarkhia came from Medieval Latin, not the other way round. The etymological information given below is "late 15th cent.: from Greek oligarkhia (probably via medieval Latin)", so it looks like a bug in generating tree diagrams from the information. It would be helpful to have the Greek, Persian, Hebrew etc. forms in the original language orthography as well instead of just the romanized transcriptions.
