Evolution of the names of metals from Proto-Indo-European to English
This person goes through the names of "iron", "lead", "copper", and "gold", tracing them from Proto-Indo-European to current American English pronunciation. He even has them in IPA! It's pretty cool :) quite unrelated to contact languages (languages in contact, languages, contacting languages, etc. etc.) but I thought it was cool. [Published on 04-14-2025]
