Why do you spell sellotape cellotape?

The spelling "cellotape" is actually the correct spelling in most parts of the world, including the UK, Australia, New Zealand, and South Africa. "Sellotape" is a trademarked name for a brand of adhesive tape made by the company Sellotape, which is a subsidiary of the 3M company.

Here's why you see different spellings:

* Trademarked vs. Generic: "Sellotape" is a brand name, while "cellotape" is a generic term for transparent adhesive tape. This is similar to how "Kleenex" is a brand name for tissues, but people use "tissue" as a generic term.

* Regional Differences: The term "cellotape" is more common in some regions, while "Sellotape" might be more common in others. This is simply due to different brand preferences and usage patterns.

So, while both spellings are technically correct, "cellotape" is generally the more widely accepted spelling as a generic term.
