What’s the Plural of Fungus: Understanding the Correct Form

• “Fungi” is the primary plural of “fungus,” following Latin rules.
• “Funguses” is a less common but acceptable plural form.
• Context and formality can influence the choice between “fungi” and “funguses.”

The principal plural form of “fungus” is “fungi,” which adheres to the classic Latin origin of the word. However, one may also encounter “funguses” as a valid yet less common alternative that follows regular English pluralization rules. The usage of either term can depend on the context or preference, but “fungi” is predominantly used in scientific and formal writing.

What’s the Plural of “Fungus”?

The plural of “fungus” can be represented as:

• Fungi: The traditional and most commonly accepted form.
• Funguses: A less common form, considered nonstandard, but understandable in modern English.

Here is a comparison of the two plural forms:

In scientific and formal contexts, “fungi” is the preferred term. It aligns with the word’s Latin roots and is widely accepted in academic writings and discussions pertaining to biology. The use of “fungi” often indicates a level of precision and respect for the word’s etymological background.

The variant “funguses,” while less standard, is not incorrect. It follows the English rule of adding “-es” to words ending in “us” to form the plural. Despite its rarity, this form appears in colloquial or less formal English usage.
