@daylight yeah but I doubt all indo-european languages did, and we know quite a bit about how sound changes worked in the germanic langauges
@Felthry yeah totally im just not a linguist lol
long, bear linguistics
@daylight we know that whatever the PIE word for bear was, it developed into "ursus" in Latin and "αρκτος" in Greek, and if you add a few other languages to the mix you should be able to get a decent enough idea of it
Looking it up on wiktionary, the reconstructed PIE word is *h₂ŕ̥tḱos (h₂ is an unknown sound thought to be a laryngeal consonant but it might also be a vowel) so if you were to bother tracing that forward through the sound changes in Germanic you'd probably get a good idea of what the word for bear was
re: long, bear linguistics, it got lewd somehow???
@daylight and in the process of trying to track down what a reasonable estimate of the norse word for bear would have been, I discovered this: https://en.wiktionary.org/wiki/%F0%90%8C%80%F0%90%8C%93%F0%90%8C%95%F0%90%8C%84%F0%90%8C%81%F0%90%8C%96%F0%90%8C%88%F0%90%8C%86#Noric
which is a Noric given name that means something like "bear penis"
@Felthry maybe but the closest languages to old norse also had this belief
