The plural can be 'octopuses', 'octopi', or, rarely, 'octopodes'. 'Octopuses' is most common in standard English. The extended meaning draws on the metaphor of tentacles reaching into many areas.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or spelling. Minor differences in the frequency of plural forms, with 'octopuses' being standard in both, though 'octopi' is a common hypercorrection.
Connotations
In both varieties, the metaphorical use (e.g., 'corporate octopus') carries a negative connotation of excessive, secretive control.
Frequency
The literal meaning is of equal frequency. The metaphorical use is slightly more common in UK political/business journalism.

Translation Traps (for Russian speakers)
- Do not directly translate as 'спрут' for the literal animal; 'спрут' is strongly metaphorical. For the literal animal, use 'осьминог'.
- The plural 'octopi' is not etymologically correct (Greek root, not Latin), but is widely used.
Common Mistakes
- Misspelling as 'octupus' or 'octapus'.
- Using the plural 'octopi' in very formal scientific writing where 'octopuses' or 'octopodes' is preferred.
- Overusing the metaphorical sense in informal contexts.

FAQ
Frequently Asked Questions
All three—'octopuses', 'octopi', and 'octopodes'—are found. 'Octopuses' follows the standard English rule for plurals and is recommended. 'Octopi' is a common hypercorrection based on Latin, and 'octopodes' follows the original Greek but is rare.
Yes, but it is rare and informal. It means to spread or extend like the tentacles of an octopus (e.g., 'The bureaucracy began to octopus into our daily lives').
Yes, octopuses are considered among the most intelligent invertebrates. They have complex brains, demonstrate problem-solving skills, use tools, and have impressive learning abilities.
The metaphor draws on the image of many tentacles grasping and controlling things from a central body. It implies an organization is expanding its control excessively and perhaps unethically into many areas.
