Syllabus or Syllabi? Clearing Up the Confusion

If you’ve ever felt puzzled by academic terms, you’re not alone. One word that often trips people up is “syllabus”—especially when it comes to its plural form. Is it syllabuses or syllabi? This isn’t just a matter of grammar; it touches on history, culture, and how the English language has evolved.

Let’s break it all down and make sense of the mystery—while also looking at what a syllabus actually is and why it matters.

📘 What Is a Syllabus?

A syllabus is a vital document in any course. Think of it as a roadmap that outlines everything a student needs to know about the class. It typically includes:

Course Description: A summary of what the class covers
Learning Objectives: What students are expected to learn
Required Materials: Books, articles, and other resources needed
Grading Policy & Schedule: How and when assignments will be assessed

In short, the syllabus helps keep both students and instructors aligned from day one. Without it, classes would feel a lot more chaotic.

🔤 Where Does the Word “Syllabus” Come From?

The word has an interesting backstory. It goes all the way back to Latin, where it was used to mean a list or label. Somewhere along the way, during the 15th century, scholars confused it with the Greek word σύλλαβος (sullabos), which means “a taking together.” That little mix-up stuck—and eventually, the word made its way into academic language as we know it today.

By the mid-1600s, “syllabus” was being used to refer to an outline of topics. Over time, as education systems grew more formal, it became the go-to term for course outlines in schools and universities.

🤔 So, What’s the Plural of Syllabus?

Here’s the part that causes the most confusion: What’s the correct plural—syllabuses or syllabi?

✔ Syllabuses

This is the standard English plural. It follows typical pluralization rules by simply adding “-es” to the end. It’s especially common in American English and is perfectly acceptable in any academic or casual context.

Example:
“Students received the syllabuses for each of their classes.”

✔ Syllabi

This form is borrowed from Latin, where some words take an “-i” ending in the plural. It sounds more formal and scholarly, so you’ll often see it used in academic circles.

Example:
“The committee reviewed all the syllabi before approving the curriculum.”

Both are correct—you can use the one that best fits your tone and audience. If you’re writing something formal or academic, syllabi might sound more polished. But if you’re aiming for clarity and accessibility, syllabuses works just fine.

What About “Syllaboi”?

You may have come across the term “syllaboi” being used as the plural of syllabus. While it might sound scholarly, it’s actually incorrect. The proper plural forms are syllabuses or syllabi—both widely accepted and grammatically accurate. Using “syllaboi” could lead to confusion and weaken the credibility of your writing, so it’s best to steer clear of it.

Understanding Plural Forms of Words Ending in “-us”

To better grasp why we say syllabuses or syllabi, it helps to look at other nouns that end in “-us.” Many of these come from Latin and follow unique plural rules:

Cactus → Cacti
Focus → Foci
Alumnus → Alumni

However, not all “-us” words follow this pattern. English also allows standard pluralization for some, which can be a bit tricky.

More Examples:

Virus → Viruses (not viri)
Octopus → Octopuses or Octopi (both are used)
Status → Statuses or Stati (though “statuses” is far more common)

As you can see, plural forms can vary depending on the word’s origin and how it has evolved in usage.

How to Use Possessives with “Syllabus” and “Syllabi”
