I feel that it’s an Americanism. In British usage, milk is whole, semi-skimmed, or skimmed. The Americanism has inflltrated Canada, too, but only the English parts, where you can buy “skim milk”. But in French, it’s still “lait écrémé”, literally “skimmed milk”. The Americanism is a short form that’s doesn’t technically make sense but has become accepted, just like how youse guys spell “colour” and “flavour” wrong. Just one of those things we have to live with.
I think most of us here prefer the Oxford comma. Hell, I was raised on AP style, which doesn’t use it, and I prefer the Oxford comma. The Chicago Manual of Style prefers it. Good enough for me.
But capitalized seasons are only okay for me if they are being personified.
That’s the advantage in being finished with college. A more relaxed writing style is fine for the majority of people. Unless your job involves professional writing.
My guess is it’s because the days of the week are considered proper names and hence capitalized, like the names of the months, whereas the season names are just generic time periods.
Apparently your teacher’s didn’t also instruct you to not throw random apostrophe’s into plural word’s, also known as the grocer’s apostrophe.
Among the crackpot theories I’ve considered: because at least some of them are named after specific individuals, like Julius Caesar and Thor, whose names are proper names.
Right, that seems to be the case. Whereas a bunch of stuff around the internet like this, whose reliability I can’t vouch for, seems to suggest that the seasons were just named for their characteristics, hence not proper names and not capitalized.
OK, another one: Capitalizing proper name initials outside of a person’s actual name, not that I think there are a lot. For example:
Kilowatt-hour is properly kWh, because “Watt” was an actual person.
Decibel is properly dB because “Bel” [sic] is none other than Alexander Graham.
I believe both of those are the way they’re usually written, but kWh is not consistent with unit prefixes on other contexts, for instance megabyte and gigabyte are usually written MB amd GB (although ironically I think megawatt is usually written mW). In the case of disk and memory sizes, there’s another convention that’s probably not rigorously followed which is that a capital “B” means “byte” and a lower-case one means “bit”.
bytes and similar are not really “scientific” or metric units, so there is no official convention to rigorously follow. Not that there is much risk of confusing bits for bels or barns. You can just write 1 Tbit/s and it is clear what you mean.
