I couldn't find a more appropriate forum than this one...
Languages are flexible things. Sure, I'll violently defend the Oxford comma, but languages change over time. That said, I've found that even English, with twice as many words as more efficient languages, doesn't have quite enough options to fully express myself. So I've made my own up over time.
What have you made up, or felt a need for? They don't have to be English. Mine are below.
Ostenstationery: ostentatious accessories, including stationery
Impostrophe: the back tick or accent that looks like an apostrophe that messes up my word documents
Demicolon: a new punctuation mark that indicates a related idea, but your original sentence was already too long. It looks like a colon with both dots replaced by commas. I could have used one before the final sentence in my first paragraph.
Dorages: door edges. Also, florages: skirting board.
