"What's the plural of vertex?"

The plural of vertex is vertices or vertexes.

Definition of vertex:

A vertex, in mathematical and geometrical contexts, refers to a point where two or more lines, edges, or curves intersect. It is often used to describe the corners or meeting points of polygons, polyhedra, or graphs.

Vertices play a crucial role in defining the shape and structure of various mathematical objects.

Is Vertex the Same as Vertices?

Yes, "vertex" and "vertices" refer to the same concept but in different forms. "Vertex" is the singular form, while "vertices" is the plural form.

It is essential to use the appropriate form based on whether you are referring to a single point of intersection (vertex) or multiple points of intersection (vertices).

Which is Correct: Vertices or Vertexes?

The correct plural form of vertex is "vertices." Following the typical rule for forming plurals in English, the "-es" suffix is added to words ending in "-ex" to indicate plurality.

While "vertexes" may be occasionally encountered, "vertices" is the preferred and more widely accepted plural form, particularly within mathematical and technical contexts.

Is Vertex a Countable or Uncountable Noun?

In grammar, nouns can be classified as either countable or uncountable. Countable nouns refer to things that can be counted as individual items, while uncountable nouns refer to things that cannot be counted or are treated as a whole.

The word "vertex" is considered a countable noun. It represents a specific point where two or more edges meet in geometry. It can be counted as individual instances when referring to multiple distinct points of intersection.

For example, you can say "There are five vertices in this polygon" to indicate the specific count of individual points.

On the other hand, uncountable nouns do not have plural forms and cannot be counted as separate entities. They represent concepts or substances that are considered as a whole. Examples of uncountable nouns include "water," "information," or "furniture."

Collective Noun for a Group of Vertices or Vertexes

There isn't a specific collective noun for a group of vertices or vertexes. However, you can use phrases like "a collection of vertices" or "a set of vertices" to refer to multiple vertices together.

These expressions effectively convey the idea of a group or assemblage of vertices.
