Plural of Octopus: English plurals can be tricky. Usually, we just add an "s" to the end of a word. One cat becomes two cats. However, words borrowed from other languages follow different rules. Some come from Greek, while others come from Latin. This makes things very confusing for writers and students alike. People often argue about the correct way to change these special words. Do you know what the plural of 'octopus' is? In this article, we'll take a look at the history and the science behind this famous word.

The plural of 'octopus' is a classic English language debate. While multiple forms are used, one is technically the most accurate based on the word's origins.
| Correct Plural | Acceptability |
| Octopuses | Recommended. This is the standard English plural. |
| Octopi | Common but incorrect. It is based on a mistaken belief that the word is Latin. |
| Octopodes | Rare. This follows the original Greek rules but is seldom used. |
Why "Octopuses" is the Winner
Here is the simple logic behind why we use these different terms:
- It's an English Word: Once a word enters the English language, it usually follows English grammar. The standard way to make a word plural in English is to add "-es" or "-s".
- The Greek Root: The word 'octopus' comes from Ancient Greek (oktōpus), not Latin. In Greek, the plural ending is "-odes". Therefore, 'octopodes' is etymologically 'more' correct than octopi.
- The Latin Myth: People often use 'octopi' because they assume the word is Latin (like 'cactus' becoming 'cacti'). However, applying Latin endings to a Greek word is considered a "linguistic error".
Note: If you want to be safe and grammatically correct, stick with octopuses. It is clear, simple, and accepted by all major dictionaries.
