When I was a kid, I learned about negative numbers pretty early on. It was a perfectly normal part of life, since the temp was in the negative a lot of the year. Made sense to me. Temp is below zero? Water is solid. . Temp above zero? Water is liquid. Fahrenheit doesn’t make much sense to me, inherently, because I don’t have an integral frame of reference, built over decades of familiarity. Celcius on the other hand, it just makes sense!
Idk about that. Probably these so called borrowed words from Italian, are actually of Latin origin, like so many words in so many European languages.
