Understanding the Plural of Scapula

If you’ve ever encountered the word “scapula” in a medical or anatomical context, you may have wondered about its correct plural form. The good news? You’re not alone! The plural of scapula is a common point of confusion. Like many words borrowed from Latin, the word “scapula” has both a Latin plural form and an Anglicized plural form.

Before we jump into the technical details, let’s first explain what a scapula is.

What is Scapula?

The scapula, commonly known as the shoulder blade, is an essential part of the anatomical structure of the upper body. It connects the upper arm bone (humerus) to the clavicle (collarbone) and plays a significant role in arm mobility and muscle attachment.

This flat, triangular-shaped bone provides a sturdy anchor for several shoulder and upper back muscles. Thanks to the scapula, we can perform a range of motions, such as lifting, rotating, and stabilizing our arms.

• Scapula = shoulder blade
• Function: Connects upper arm bone to the clavicle and supports muscle attachment for upper body movement.

Understanding this term’s function will help you understand why pluralization is relevant in anatomy and medical fields.

Origins of the Word “Scapula”

The word scapula is in Latin, meaning “shoulder blade” or “spade.” Its usage dates back to Ancient Rome when the word was used to describe a flat, broad surface. Over time, the word became a staple in medical terminology, particularly in studying anatomical structures.

• Etymology: From the Latin term “scapula,” meaning shoulder blade.
• Modern use: Primarily found in medical language and clinical lexicons.

Because of its Latin origin, the pluralization of “scapula” can follow either Latin pluralization rules or the more common English plural rules.

Pluralization Rules for Words Ending with “-la”

Words like “scapula,” which end in “-la,” have two potential plural forms: one that adheres to Latin grammatical conventions and one that follows standard English language rules.

This section will examine the specific pluralization rules that apply to words ending in “-la.”

-la to -lae: The Latin Plural Rule

In classical Latin, the plural form of words ending in “-la” is formed by replacing “-la” with “-lae.” This pattern is prevalent in medical and scientific fields, where the Latin language has had a profound influence.

• Example: Scapula → Scapulae
• Usage: This form is typically used in formal medical writing or scientific discussions.

-la to -las: The English Plural Rule

Alternatively, words like “scapula” can take the English plural form by simply adding an “s” to the end of the word. This form is more common in casual conversation or non-medical contexts.

• Example: Scapula → Scapulas
• Usage: This form is widely accepted in everyday language and informal writing.

You can use scapulae or scapulas by understanding these two rules, depending on the context.

Exceptions to These Pluralization Rules

Of course, no set of grammar rules is without its exceptions. While most words ending in “-la” follow the above pluralization patterns, there are some notable exceptions where the plural forms differ. These irregularities typically result from historical usage, language evolution, or simply being irregular plural forms.

Singular and Plural Same

Some words maintain the same form for both their singular and plural uses. This phenomenon is rare in medical or scientific terminology, but it is not uncommon in the English language, more broadly.

• Example: Species (singular) → Species (plural)
• Example: Deer (singular) → Deer (plural)

Irregular Plural Forms

Additionally, some words form their plurals unexpectedly, deviating from standard pluralization rules.

• Example: Child → Children
• Example: Tooth → Teeth

Words with English Plurals

While Latin pluralization rules are often used in medical and scientific contexts, many anatomical terms have been fully adopted into  English, where they follow standard English plural rules. For instance, words like scapula, formula, and vertebra can take on English plurals like scapulas, formulas, and vertebras.

Understanding when to use the Latin or  English plural can help you navigate technical writing and everyday communication.

• Example: Vertebra → Vertebras (English) or Vertebrae (Latin)
• Example: Formula → Formulas (English) or Formulae (Latin)

Words Ending in “-ula”

Many medical terms ending in “-ula” follow similar pluralization patterns as scapula. These terms often originate from Latin and are used in anatomy to describe specific parts of the body.

• Example: Fistula → Fistulae/Fistulas
• Example: Papilla → Papillae/Papillas

Just like “scapula,” these words can have either a Latin plural or an English plural, depending on the context in which they’re used.

Word	Latin Plural	English Plural
Scapula	Scapulae	Scapulas
Fistula	Fistulae	Fistulas
Papilla	Papillae	Papillas

Plural of Scapula: When to Use Scapulae vs. Scapulas

Now that we’ve reviewed the pluralization rules, let’s focus on when to use scapulae and scapulas in real-life contexts.

Scapulae: Formal and Medical Use

The Latin plural scapulae is preferred in formal writing, especially in medical terminology. If you’re writing a research paper or discussing anatomy in a professional setting, scapulae is the appropriate choice.

• Example in a Sentence: The patient’s scapulae showed no signs of injury in the X-ray.

Scapulas: Informal and Casual Use

Anglicized plural scapulas are acceptable in informal contexts or everyday speech. They are more accessible for most people and are more common in casual conversation.

• Example in a Sentence: My scapulas hurt after yesterday’s workout.

Both forms are correct, but knowing when to use which form will help you communicate more effectively, especially in medical language.

Some Nouns Ending with “-la” and Their Plurals

Here’s a table that shows some common anatomical terms and their plural forms. Use this as a reference when encountering similar words.

Singular	Plural (Latin)	Plural (English)
Scapula	Scapulae	Scapulas
Vertebra	Vertebrae	Vertebras
Formula	Formulae	Formulas

Examples in Context: Using Scapula, Scapulae, and Scapulas

To help you understand when to use scapula, scapulae, and scapulas, let’s explore some real-life examples.

Scapula: The Singular Form

• Example: The doctor explained that the scapula is a crucial part of the shoulder bone.

Scapulae: The Latin Plural Form

• Example: Upon examining the patient’s X-ray, the physician noted abnormalities in both scapulae.

Scapulas: The English Plural Form

• Example: After the intense workout, John complained that his scapulas were sore from lifting weights.

In each of these examples, the form of the word changes based on the context in which it’s used.

Medical Terminology and Pluralization in Anatomy

In medical terminology, understanding pluralization rules is essential. Medical professionals need to communicate accurately about the body’s anatomical structure, so distinguishing between singular and plural forms of terms like scapula is critical.

Terms like scapulae are used in clinical lexicons and medical jargon, but it’s also crucial to recognize when to use more familiar terms like scapulas in conversation with patients.

Bonus Tips: How to Remember the Plural of Scapula

Struggling to remember whether to use scapulae or scapulas? Here are a few bonus tips that might help:

• Mnemonic for Scapulae: Think of scapulae like “algae”—both are plural forms that end in “-ae”.
