Ever been reading a history book and hit those two little letters—AD—and wondered if you’re actually supposed to say the full Latin phrase out loud? It’s one of those weird things. We see it everywhere. It's on cornerstones of old buildings and in every textbook from middle school. But saying it? That's a different story. Honestly, most people just mumble "A-D" and move on with their lives, which is totally fine, but there is a right way and a very wrong way to handle the linguistics here.
Latin is tricky. It’s a "dead" language, but it’s still breathing down our necks in legal documents, medical charts, and, of course, our calendar. When you’re trying to figure out how to say anno domini, you aren't just looking for a pronunciation guide. You’re navigating a minefield of ecclesiastical tradition, academic preference, and the modern shift toward secularism.
The Phonetics: Getting the Latin Right
First, let's just kill the suspense. If you want to say the whole thing, it’s An-no Dom-in-ee.
Some people try to get fancy with the "Domini" part. They might say Dom-in-eye. That’s usually the "Great Vowel Shift" messing with your head—the same reason we say "alibi" with a long i at the end. But in Classical or Ecclesiastical Latin, that final i is a long e sound. Think of the word "tree."
So, it's Anno (like the word "annual" but with an o) and Domini (like "dominate" but ending in "knee").
Simple? Kinda.
But wait. There’s a grammatical quirk that drives historians crazy. Most people say "the year of our Lord, 2026." In Latin, Anno Domini literally translates to "in the year of the Lord." Because the word Anno is already in the ablative case, you don’t actually need to add the word "in" before it. Saying "In Anno Domini 1492" is technically saying "In in the year of the Lord 1492." It's redundant. If you want to sound like a total pro at a dinner party (or a really intense trivia night), just drop the "in."
Just say: "The event occurred Anno Domini 476."
Why the Word Order Matters (and Why We Usually Get it Wrong)
Here is a fun fact that almost everyone misses.
With BC (Before Christ), the letters go after the year. 300 BC. That makes sense. It’s how we talk. But with AD, the traditional rule is that the letters go before the year.

AD 2026.
Why? Because of the translation. You wouldn't say "2026 in the year of our Lord." You’d say "In the year of our Lord 2026."
However, language is a living, breathing mess. Almost everyone puts AD after the number now. If you do that, you aren't "wrong" in the sense that people won't understand you, but you are "wrong" in the eyes of the Chicago Manual of Style or the AP Stylebook. If you're writing a thesis or trying to impress a monk, put the AD first.
The Great CE vs. AD Debate
You’ve probably noticed that a lot of museums and Netflix documentaries have stopped using AD entirely. They use CE.
CE stands for "Common Era."
If you’re wondering how to say anno domini in a professional or scientific setting today, the answer might actually be: don't. A lot of academics have moved to BCE (Before Common Era) and CE to keep things secular. It uses the exact same dating system—the Gregorian calendar—but strips away the religious title.
This isn't just a modern "woke" thing, either. Kepler was using the term Vulgaris Aerae (Vulgar Era/Common Era) back in the 1600s. He wasn't trying to be politically correct; he just recognized that not everyone using the calendar was a Christian.
So, which one should you use?
- Use AD if you are writing for a religious publication or a traditional history journal.
- Use CE if you are writing for a scientific paper, a global audience, or a secular university.
- Use neither if the context is obvious. If you say "The Declaration of Independence was signed in 1776," no one is going to ask if you mean BC or AD.
Historical Context: Where Did This Even Come From?
We owe this whole headache to a monk named Dionysius Exiguus. He was living in Rome around 525 AD. At the time, the Romans were dating things based on the reign of Emperor Diocletian. The problem? Diocletian was a massive fan of persecuting Christians.

Dionysius didn't want to keep the memory of a tyrant alive every time he checked his calendar. He decided to re-center history around the birth of Jesus.
The catch? He was probably off by a few years. Most modern historians and biblical scholars (like those cited in the Oxford Annotated Bible) suggest that if Jesus was a real historical figure, he was likely born between 6 BC and 4 BC.
This means that if you say "Anno Domini," you are technically using a calendar that might be "wrong" about its own starting point by about half a decade. But that's history for you. It's messy.
Practical Tips for Your Vocabulary
If you’re reading a text out loud—maybe you’re a teacher or you’re recording an audiobook—and you see "AD," you have three choices for how to say it.
Option A: The Literal Approach. Just say the letters. "A.D." It’s the most common, it’s fast, and everyone knows what it means. It’s never wrong.
Option B: The Formal Expansion. Say "Anno Domini." Use this if you want to sound authoritative or if the text is particularly formal. It adds a bit of "weight" to the sentence.
Option C: The Translation. Say "In the year of our Lord." This is very common in liturgical settings (church) or when reading older, more poetic historical documents.
Is there a "correct" one? Not really. It’s all about the vibe of the room.
Beyond the Basics: Related Latin Terms You’ll See
While we’re talking about how to say anno domini, we should probably look at its cousins. You’ll see these in the same types of books.

- Circa (c. or ca.): This means "around." If you see "c. 1200," say "Circa twelve hundred" or just "Around twelve hundred."
- Floruit (fl.): This is used for people where we don't know their birth or death dates, only when they were "active." It means "he/she flourished." If you see "fl. 1350," you can literally say "flourished in thirteen fifty."
- Et alibi (et al.): You usually see this in citations. It means "and others."
Actionable Steps for Using These Terms Correctly
If you want to master the use of historical dating in your own writing or speech, here is how you do it without looking like you're trying too hard.
Check your style guide. If you’re a student, ask if your professor prefers BCE/CE or BC/AD. Most universities are leaning toward CE now. If you're writing for a hobby blog, stick to BC/AD—it’s more recognizable to the general public.
Watch your placement. Remember: AD goes before the year (AD 1066), BC goes after (300 BC). It’s a small detail, but it’s the hallmark of a polished writer.
Don't over-pronounce. If you choose to say the full Latin, keep it casual. An-no Dom-in-ee. Don't put a fake Italian or Latin accent on it. Just say it like you'd say any other English word.
Know your audience. If you’re talking to a group of historians, using "CE" shows you’re up to date with modern standards. If you’re at a traditional church function, "Anno Domini" is much more appropriate.
Ultimately, the goal of language is to be understood. Whether you say "A-D," "Anno Domini," or "Common Era," the point is that we're all talking about the same stretch of human history. Dionysius Exiguus might have been off by four years, and his Latin might be a bit clunky for the 21st century, but his system stuck.
Next time you see those two letters, you don't have to stumble. You know the history, you know the grammar, and you definitely know the pronunciation.
