Definition of Vertex

A vertex (plural: vertices or vertexes) is a point where two or more lines, curves, or edges meet. The term originates from Latin, where it means “summit” or “highest point.” The word is commonly used in a variety of fields, including mathematics, geometry, computer science, and even anatomy.

In mathematics, a vertex is often referred to as a point where two lines intersect, forming an angle. In the context of graphs, a vertex (also called a node) represents a fundamental unit within the graph structure. In geometry, a vertex is a corner point of a polygon, polyhedron, or other geometric shape. For example, a triangle has three vertices, while a cube has eight. In computer science, especially in graph theory and computer graphics, vertices are fundamental components of graphs and 3D models.

The function of a vertex is to define the corners or points of intersection in a shape or structure. It’s a foundational element for describing and analyzing geometric and structural properties. Understanding the concept of a vertex is essential for grasping more complex concepts in these fields.

Structural Breakdown

The word “vertex” follows Latin noun declension patterns. This means its pluralization isn’t as straightforward as simply adding an “-s” at the end. The standard plural form, “vertices,” adheres to the Latin rule of changing the “-ex” ending to “-ices.” This pattern is commonly seen in other Latin-derived words like “index” (indices) and “matrix” (matrices).

However, English also allows for the anglicized plural form “vertexes,” which is created by adding “-es” to the singular form. This anglicized form is considered acceptable, especially in less formal contexts. The choice between “vertices” and “vertexes” often depends on the level of formality and the specific field of study.

The key structural components are the root word “vertex” and the suffixes “-ices” and “-es” that create the plural forms. Understanding the Latin origin helps explain the existence of “vertices,” while recognizing the anglicization process clarifies the acceptance of “vertexes.”

Plural Forms: Vertices and Vertexes

As mentioned earlier, “vertex” has two accepted plural forms: “vertices” and “vertexes.” Both are grammatically correct, but they are used in different contexts and carry slightly different connotations.

Vertices

Vertices is the more traditional and formal plural form. It adheres to the original Latin declension rules. This form is generally preferred in academic writing, scientific publications, and other formal settings. It is the standard plural in mathematics and geometry.

The use of “vertices” demonstrates a knowledge of Latin roots and a commitment to grammatical precision. It’s the form you’re most likely to encounter in textbooks, research papers, and professional presentations.

Vertexes

Vertexes is the anglicized plural form. It’s created by simply adding “-es” to the singular form “vertex.” This form is more common in informal contexts and is often considered acceptable in general writing. While not as widely used in highly technical fields, its usage is increasing, and is perfectly acceptable.

The use of “vertexes” is often seen as more accessible and less pretentious than “vertices.” It’s a perfectly valid option, especially when writing for a general audience or in less formal settings. It is more common to see this form used in general language or less technical publications.

Examples of Usage

To further illustrate the usage of “vertices” and “vertexes,” here are several examples categorized by field:

Usage Rules

The proper use of “vertices” and “vertexes” depends on several factors, including the context, audience, and level of formality. Here are some general guidelines to follow:

Formal vs. Informal Contexts

In formal writing, academic papers, and technical publications, “vertices” is generally the preferred form. This is because it adheres to the Latin origin of the word and is considered more precise. In informal settings or when writing for a general audience, “vertexes” is acceptable and may even be preferred for its simplicity.

Singular vs. Plural Context

Ensure that you use the correct form depending on whether you are referring to one vertex or multiple vertices/vertexes. The singular form is always “vertex.” The plural forms, “vertices” and “vertexes,” should be used when referring to two or more vertices.

Consistency in Writing

Regardless of which form you choose, maintain consistency throughout your writing. Avoid switching between “vertices” and “vertexes” within the same document or article unless there is a specific reason to do so. Select the form most appropriate for your audience and stick with it.

Common Mistakes

One common mistake is using “vertexs” as the plural form. This is incorrect; the correct plural forms are “vertices” and “vertexes.” Another mistake is using the singular form “vertex” when referring to multiple points.

Advanced Topics

For those looking to delve deeper into the topic, here are some advanced considerations related to “vertex.”

Etymology of Vertex

The word “vertex” comes from the Latin word vertex, which means “whirlpool,” “summit,” or “highest point.” This origin helps explain its use in various fields to describe points of convergence or high points.

Understanding related terms can further enhance your comprehension of “vertex.” Some related terms include:

  • Node: Often used interchangeably with “vertex” in graph theory.
  • Apex: Similar to “vertex,” meaning the highest point.
  • Corner: A common term for a vertex in geometric shapes.
  • Intersection: The point where lines or curves meet, forming a vertex.

Frequently Asked Questions

Here are some frequently asked questions about the plural of “vertex”:

  1. Is “vertexes” a real word?
    Yes, “vertexes” is a recognized plural form of “vertex,” although it’s less common and more informal than “vertices.”
  2. Which plural form should I use, “vertices” or “vertexes”?
    In formal writing and technical contexts, “vertices” is generally preferred. In informal settings, “vertexes” is acceptable.
  3. Can I use “vertexs” as the plural?
    No, “vertexs” is not a correct plural form. The correct plural forms are “vertices” and “vertexes.”
  4. What does “vertex” mean in geometry?
    In geometry, a vertex is a corner point of a polygon, polyhedron, or other geometric shape.
  5. What does “vertex” mean in computer science?
    In computer science, particularly in graph theory and computer graphics, a vertex (or node) represents a fundamental unit within a graph or 3D model.
  6. Why does “vertex” have two plural forms?
    The existence of two plural forms is due to the word’s Latin origin and its subsequent anglicization. “Vertices” follows the Latin declension rule, while “vertexes” is formed by adding the English plural suffix “-es.”
  7. Is it acceptable
    to use “vertexes” in a scientific paper?
    While “vertices” is more common and preferred in scientific papers, “vertexes” is generally acceptable as long as its usage is consistent throughout the paper. However, it’s always best to adhere to the specific guidelines or style manual recommended by the publication.

Conclusion

Understanding the plural of “vertex” is essential for clear and accurate communication, especially in technical fields like mathematics, geometry, and computer science. While “vertices” is the more traditional and formal plural, “vertexes” is also acceptable, particularly in informal contexts. By following the guidelines and examples provided in this article, you can confidently use both forms correctly. Remember to consider your audience, the level of formality, and the need for consistency in your writing. With this knowledge, you’ll be well-equipped to navigate the nuances of “vertex” and its plural forms in any situation.
