Many English learners, writers, and even native speakers often search for “gases or gasses” because both spellings appear online, in books, and in everyday writing. This creates real confusion.
If you are writing an email, an academic paper, a blog post, or technical content, choosing the wrong spelling can reduce clarity and credibility.
The confusion happens because English has many plural rules, and not all words follow the same pattern.
At first glance, gas → gasses looks logical, just like glass → glasses. However, English spelling rules are shaped by history, pronunciation, and usage patterns, not logic alone.
Search engines, spell-checkers, and style guides often disagree, which makes people double-check.
This article solves that confusion completely. You will learn the correct spelling, where each form comes from, how British and American English treat it, and which version you should use for your audience.
By the end, you will know when gases is right, when gasses is acceptable, and how to avoid common mistakes with confidence.
Quick Answer
“Gases” is the correct plural form of “gas” in modern English.
It is the standard spelling used in science, education, journalism, and professional writing.
“Gasses” is not the plural noun. It is mainly used as a verb (third-person singular), meaning to release gas.
Examples:
- ✅ The lab studied several industrial gases.
- ❌ The lab studied several industrial gasses. (incorrect noun use)
- ✅ The factory gasses the chamber to remove oxygen. (verb use)
Quick rule:
- Plural noun → gases
- Verb form → gasses
The Origin of Gases or Gasses
The word gas comes from the 17th century. It was introduced by the Flemish chemist Jan Baptist van Helmont, who used it to describe invisible substances released during chemical reactions.
The term likely came from the Greek word chaos, meaning empty space.
When English adopted the word, it followed pronunciation-based plural rules rather than visual spelling rules.
Even though gas ends in -s, its plural became gases, not gasses. This mirrors words like:
- bus → buses
- lens → lenses
The spelling “gasses” developed later as a verb form. English often doubles consonants when adding -es to verbs for clarity in pronunciation. Over time, both spellings survived but took different grammatical roles, which is why confusion still exists today.
British English vs American English Spelling
Both British English and American English agree on the correct plural noun spelling.
- British English: gases
- American English: gases
There is no regional spelling difference for the plural noun.

| Form | British English | American English | Correct Use |
| gases | ✅ Yes | ✅ Yes | Plural noun |

Which Spelling Should You Use?
Your choice depends on grammar, not location.
- For US audiences: Use gases (plural noun)

Use “gasses” only when you mean an action, not a thing.
