Yes, but I'm still interested in the origin of the word cellotape, which is used by some in the English-speaking world, chiefly perhaps in the U.K., while others use the descriptors sellotape (with the first letter either capitalized or lower case), sticky tape, or (at least in North America) scotch tape, all in reference to the cellophane transparent adhesive tape invented in 1930 or so.

When I search for "origin of the word cellotape" on Google I get "Did you mean: origin of the word sellotape?"

When I click on an article supposedly containing the word cellotape, the link is to this one in which it's the word sellotape being used in an article describing some very unsavory business practices.

When I click on another of those anecdotal blog discussions, I see some anonymous contributors referring to it as "sellotape" and some as "cellotape." Of course this FT thread appears on the same search.

I also find a 2003 BBC article, A brief history of sticky tape, the first two lines of which read:

When I go to the U.K. Google site, I find another question-and-answer site that replies to the question "Is it sellotape or cellotape?" as follows:

I'm old enough to recall when older people used to call electric refrigerators "iceboxes" because that's what they'd been accustomed to, and when some people called them "frigidaires," after the popular brand, just as other popular brand names, e.g. kleenex for facial tissue, scotch tape for cellophane tape, become the generic name of the item. As a new member just pointed out, companies and organizations often fight to maintain their proprietary rights in regard to names.

I've already read more about sellotape and cellotape than I would have ever thought, but questions still remains in my head that I can't find and that nobody has answered definitively with reference sources:

Which word came first - cellotape or sellotape?

Was one derived from the other?

Mrs. Fredd will gladly confirm any and all further references to my ignorance and stupidity.
