I was speaking Spanish to my friend from Mexico and he mentioned something about bears “invernando”. I immediately made the connection and realized that this meant “hibernating”, and I was completely mindblown because I had never made the connection between those two words before! They actually look quite similar:
Of course, we have to take into account the silent h, and the b-v change… but you can kind of see how the words are drawn from the same root.
It also makes total sense, since “invierno” means winter.
Upon further research, I discovered that “hibernar” is also an acceptable translation, though I’m not sure which one is more common.
