Medium Plural Form: Rule, Examples, and Mistakes
If you are writing about a spiritualist, a size of clothing, or a method of communication, the plural of medium is not always the same word. The correct plural depends entirely on the meaning you intend. For a person who claims to communicate with spirits, the plural is mediums. For a size between small and large, the plural is mediums. For a channel of communication or an artistic material, the plural is usually media. This guide explains each rule with clear examples, common mistakes, and practical advice for real writing.
Quick Answer: Which Plural Should You Use?
- Mediums – Use for people (spiritual mediums) and for sizes (clothing sizes, drink sizes).
- Media – Use for communication channels (news media, social media), artistic materials (paint, clay), and scientific growth substances (bacteria culture media).
- Mediums is also acceptable in some technical contexts, but media is the standard academic plural for the communication and art senses.
Understanding the Two Plurals
The word medium comes from Latin, where the plural is media. English has kept this Latin plural for abstract and collective meanings. However, English also applies the regular -s plural for concrete, countable meanings. This split causes confusion even for native speakers.
When to Use “Mediums”
Use mediums when you are talking about individual, countable items or people.
- Spiritual mediums: People who claim to communicate with the dead. Example: Three mediums attended the conference.
- Clothing or drink sizes: A size between small and large. Example: The store sells smalls, mediums, and larges.
- Specific growth media in biology (sometimes): Some scientific writers use mediums when referring to distinct types of growth substances. Example: The lab tested five different culture mediums. However, media is more common in formal scientific writing.
When to Use “Media”
Use media for collective or abstract concepts, especially in academic and formal contexts.
- Communication channels: Television, radio, newspapers, the internet. Example: The media covered the election thoroughly.
- Artistic materials: Oil paint, watercolor, charcoal, digital tools. Example: She works in several media, including acrylic and pastel.
- Scientific growth substances: Nutrient solutions for bacteria or cells. Example: Bacteria were cultured in liquid media.
- Data storage: Physical formats like CDs, DVDs, USB drives. Example: Back up your files on multiple media.

Common Mistakes
Even careful writers make these errors. Here are the most frequent ones.
Mistake 1: Using “Media” for People
Incorrect: She is one of the most famous media in the country.
Correct: She is one of the most famous mediums in the country.
Why: Media refers to communication channels, not people. A spiritualist is a medium, and the plural is mediums.
Mistake 2: Using “Mediums” for Communication Channels
Incorrect: Social mediums are changing how we interact.
Correct: Social media are changing how we interact.
Why: Social media is a fixed term. Using mediums here sounds unnatural and non-standard.
Mistake 3: Treating “Media” as Always Singular
Incorrect: The media is biased. (In formal academic writing, media is plural.)
Correct: The media are biased. (Formal) OR The media is biased. (Informal, increasingly accepted)
Why: In strict formal English, media is the plural of medium. However, in everyday conversation, media is often treated as a singular mass noun. For academic writing, use the plural verb.
Mistake 4: Confusing “Medium” with “Median”
Incorrect: The medium of the data set is 45.
Correct: The median of the data set is 45.
Why: Medium means middle in size or a channel. Median is a statistical term for the middle value.
Better Alternatives and When to Use Them
Sometimes you can avoid the confusion entirely by choosing a different word.
- Instead of “mediums” (people): Use psychics, channels, or spiritualists. Example: Three psychics gave readings.
- Instead of “media” (communication): Use news outlets, platforms, or channels. Example: News outlets covered the story.
- Instead of “media” (art): Use materials or techniques. Example: She uses watercolor and charcoal materials.
- Instead of “mediums” (sizes): Use size M or middle sizes. Example: We need more size M shirts.
These alternatives are especially useful in formal emails or academic papers where precision matters.

FAQ: Medium Plural
1. Is “media” singular or plural?
Strictly, media is the plural of medium. In formal academic writing, use a plural verb: The media are influential. In informal conversation, many people treat media as a singular mass noun: The media is biased. For your academic work, stick with the plural verb.
2. Can I use “mediums” for social media?
No. Social media is a fixed term. Using social mediums will sound incorrect to most readers. Always use social media.
3. What is the plural of “medium” in art?
The standard plural is media. For example: Oil and acrylic are two different media. Some artists use mediums when referring to specific types of paint, but media is more common in formal art criticism and education.
4. Why does “medium” have two plurals?
Because English borrowed the word from Latin. The Latin plural media is used for abstract, collective, and technical meanings. The English regular plural mediums is used for concrete, countable meanings like people and sizes. This split is common with Latin loanwords (e.g., criterion/criteria, datum/data).
Final Advice for Real Writing
When you are writing an email, an essay, or a report, ask yourself: Am I talking about people, sizes, or specific items? If yes, use mediums. Am I talking about communication, art, or science? If yes, use media. This simple question will guide you correctly almost every time. For academic writing, prefer media for all abstract and collective senses, and use mediums only for people and sizes. If you are ever unsure, check the context of your sentence and choose the form that matches the meaning.
