Whats the Plural of Paralysis: Understanding Grammatical Nuances

• The plural of “paralysis” is “paralyses.”
• English nouns ending in “-sis” often change to “-ses” for the plural form.
• Proper usage of “paralysis” and “paralyses” depends on context.

The plural form of “paralysis” is “paralyses.” This transformation follows a pattern observed in many English nouns ending in “-sis,” where the pluralization involves changing “-sis” to “-ses.” The usage of “paralysis” and “paralyses” in sentences must align with their singular and plural contexts, respectively, which impacts the meaning conveyed.

What’s the Plural of “Paralysis”?

The change occurs in the last part of the word:

• Singular: Paralysis
• Plural: Paralyses

Here is an illustration of the transformation:

Singular	Plural
-is	-ises

In this scenario, the ending “-is” is dropped and replaced with “-ises” to form the plural.

Contrast this with regular pluralization in English, demonstrated below:

Singular	Regular Plural Formation	Plural
book	book + s	books
cat	cat + s	cats
bus	bus + es	buses

On the other hand, “paralysis” is an example of a term that does not follow this regular pattern. It is essential to memorize these exceptions to use them correctly in speech and writing.

• Examples of usage:
  • The clinic specializes in the treatment of various paralyses.
  • During the seminar, they discussed the causes of different types of paralyses.

Nouns That End in -sis/-ses

When it comes to English nouns that end with the suffix “-sis,” such as “paralysis,” the plural form is typically made by changing this suffix to “-ses.” These nouns often refer to actions, processes, diseases, or states. The transformation follows a classical Greek conjugation pattern, which can be confusing because it deviates from the more common pluralization rule of simply adding an “s” or “es.”

Common Examples:

Singular	Plural
analysis	analyses
crisis	crises
thesis	theses
basis	bases

This table illustrates how several words adhere to the pattern where the “is” is substituted with “es” to form the plural, a pattern that is consistent among such nouns.

Some nouns have both countable and uncountable variations. In their uncountable form, these words might seem to retain the same spelling in both singular and plural:

• Diagnosis (uncountable: remains the same)
• Hypothesis (countable: changes to hypotheses)

Rules to Remember:

• Nouns ending in “-sis” change to “-ses” in the plural.
• The change applies even if the word is rarely used in the plural form.
• Some nouns are both countable and uncountable, affecting their pluralization.
