It didn't look very much like Latin to the Romans, either. It's used in bits and pieces of really old (i.e., older than usual) Latin poetry that happen to survive only because an ancient lexicographer named Verrius Flaccus quoted them. Verrius Flaccus is an important guy, and there's even a street named after him in Palestrina:
topper. Later writers abridged him, until eventually Paulus Diaconus in the 8th century CE winnowed the definition to a single word: "fast."
I have a friend (not the ex-boyfriend, ugh) whose last name is "Topper." And here is a limerick I wrote for that friend, whom I will call "John":
There's an entry in Paulus' epitomeCome on, reader: you know the rhymes in lines 1, 2 and 5 are brilliant.
Where of all topper's meanings, that litany,
One sense, that of "fast,"
All the rest. But John just says, "What's it to me?"
