Crisis Plural Form: Rule, Examples, and Mistakes
The plural form of crisis is crises. This follows the rule for many English nouns ending in -is that come from Greek, where the -is changes to -es in the plural. So you write one crisis but two crises. This is a fixed spelling rule, not a choice, and using the wrong form is a common mistake in business writing.
Quick Answer: Crisis vs. Crises
Use crisis for a single event or situation. Use crises for two or more. The word crisises does not exist in standard English. Always check the number of events before you write.
- Singular: crisis
- Plural: crises
- Pronunciation: crisis = KRY-sis; crises = KRY-seez
Why the Spelling Changes
Many English words that end in -is come from Greek. The plural pattern is to replace -is with -es. Other common examples include thesis (theses), analysis (analyses), and hypothesis (hypotheses). Once you learn this pattern, you can apply it to any similar word you meet in business or academic reading.

Common Mistakes with Crisis and Crises
Even experienced writers make errors with these words. Here are the most frequent mistakes and how to fix them.

Right: The company faced two crises.
Mistake 2: Using “crises” for a single event
If there is only one problem, use crisis.

In conversation, saying crises like crisis can confuse listeners. The vowel sound changes. Practice saying crises with a long ee sound at the end.
