Most of these technically aren't acronyms. It's only an acronym if it forms (and can be spoken as) a word; like "nasa" or "peta" or "awol". If you just speak the letters then its just an initilism; like "BBC" or "USSR". The weird one is always UFO; it's an initilism because most people say UFO, but the guy who came up with it ended for it to be an acronym, pronounced as Ufo. Juts a little bit of knowledge for you all there.

Actually, initialisms are a subset of acronyms. That is to say, USSR is both an acronym and an initialism, while NASA is only an acronym.

There's a list of acronyms on Wikipedia. NSFW is not on there in case you were wondering. It's categorized as Internet slang. Anyway: NSFW means Not Safe For Work. And it is exactly what it says: Material containing nudity, pornography etc. I've seen it being used for violent content as well. Kind of like a spoiler alert.

Just a general point; there is a difference between an acronym and an abbreviation. If you pronounce the letters individually, this is not an acronym. An acronym is when a new word is formed, for example "SCUBA".

ICBM, ADHD, etc are abbreviations, NOT acronyms.

+1
Level 77
Dec 14, 2022
Are you sure this is not rather referring to Jesus? When thinking of a person living 2000 years ago, that is usually what comes to mind first. Caesar obviously lived a little before that, say, 2070 years ago. Besides, I don't think Caesar is often referred to as Julius.

It has always been possible along with small bold and cursive etc.

I ve posted at least one picture in the comments on jetpunk (I think two but can only remember what one was, a slice of earthcake). (Ow wait I remember what the other was, someone thought Malaysia looked like something and I thought it looked like wajang puppet and found one that looked almost exactly like it)

but don't want to burden the servers so those have been the only two times. When words couldn't explain it.

How is that a question? OK weird scenario comes to me as an answer... like someone walking in on their parents an seeing (inexplicable) things and saying omfg and having a lot of questions ..

about gods in roman times there was much more clarity shall we say. (When? Whenever possible, who? Doesn't matter)

HTTPS is the standard but you can still navigate with HTTP and find domains that didn't purchase the SSL. Definitely not the Quizmaster's best hint. Quizmaster - consider changing it to something that doesn't imply an absolute condition like, "Common protocol that comes before www in a URL"?
