In the English language, the words “crises” and “crisis” are often used interchangeably, but they have distinct meanings and usage. Understanding when to use each one correctly is crucial for effective communication. In this comprehensive guide, we will explore the differences between “crises” and “crisis” and provide examples to illustrate their proper usage.


Both “crisis” and “crises” are correct terms in American English, but they have subtle differences in meaning. To use these words appropriately, it is essential to understand their definitions and how they are used in various contexts. Let’s explore the nuances of “crisis” and “crises” in more detail.

Definition of Crisis

The term “crisis” is a singular noun that refers to a significant event or situation characterized by intense difficulty, danger, or uncertainty. It typically conveys a sense of urgency and requires immediate attention or resolution. A crisis can occur in various domains, such as politics, economics, society, or personal life.

Definition of Crises

On the other hand, “crises” is the plural form of “crisis.” It refers to multiple instances of challenging or perilous events. When we use “crises,” we are discussing more than one crisis. The plural form is used to indicate that there are multiple distinct occurrences of difficulties or emergencies.

Examples of Crisis

To understand the usage of “crisis,” let’s look at some examples that highlight its singular form:

  1. “The country is facing an environmental crisis due to pollution and deforestation.”
  2. “The company experienced a financial crisis after the stock market crash.”
  3. “Her sudden illness caused a personal crisis for the entire family.”
  4. “The government declared a state of emergency in response to the healthcare crisis.”

In each of these examples, “crisis” refers to a specific event or situation that demands immediate attention or resolution.

Examples of Crises

Now, let’s explore the usage of “crises” by examining some examples that demonstrate its plural form:

  1. “The world is currently grappling with multiple humanitarian crises, including armed conflicts and natural disasters.”
  2. “The organization responded to the economic crises in different countries by providing financial aid and support.”
  3. “Throughout history, societies have faced various political crises that have challenged their stability and governance.”
  4. “The medical field encounters numerous health crises, such as pandemics, outbreaks, and epidemics.”

In these instances, “crises” denotes multiple distinct events or situations that require attention or resolution.

Pluralization of Crisis

The pluralization of “crisis” as “crises” follows a specific pattern observed in many English words derived from Greek and ending in “-sis.” This irregular pluralization involves changing the final “-is” to “-es.” Other examples of nouns that follow this pattern include “oasis” (oases), “thesis” (theses), and “analysis” (analyses).

Pluralization of Crises

To pluralize “crises,” no further changes are needed as it is already in its plural form. It is important to note that “crisises” is not a recognized plural form of “crisis.” The irregular plural pattern observed in words derived from Greek and ending in “-sis” applies to “crisis” and not its plural counterpart.

Confusion and Common Mistakes

The proper usage of “crisis” and “crises” can be confusing for some due to their similar spellings and the presence of the letter “s” at the end of “crisis.” However, it is essential to understand that “crisis” is singular, while “crises” is plural.

Common mistakes occur when individuals use “crisises” as the plural form of “crisis,” which is incorrect. Familiarity with the irregular plural pattern of nouns derived from Greek, such as “crisis,” can help avoid such errors.


In summary, “crisis” and “crises” are distinct terms with separate meanings and uses. “Crisis” is a singular noun referring to a significant event or situation, while “crises” is its plural form, denoting multiple instances of challenging or perilous events. Understanding the difference between these two terms is crucial for clear and effective communication.
