Subject: 7) Plural of LEGO
While most people point out that they just say LEGOs, lunatic@netcom.com (Lunatic Johnathan Bruce E'Sex) dug out:

One catalogue, dated 1980, has the following on its back page:

    Dear Parents and Children
    The word LEGO(R) is a brand name and is very special to all of us in the LEGO Group Companies. We would sincerely like your help in keeping it special. Please always refer to our bricks as 'LEGO Bricks or Toys' and not 'LEGOS.' By doing so, you will be helping to protect and preserve a brand of which we are very proud and that stands for quality the world over. Thank you!

Matthew Miller, mattdm@mattdm.org, added:
The above quote from the catalog is often cited as evidence for "Lego" as the proper plural, but in fact that is misreading it. Trademark law in the US at least is easiest if the trademark is used as an _adjective_. The point they're trying to make is that you should say "LEGO Bricks", rather than calling the product itself either "Legos" _or_ "Lego".

In fact, they seem to assume that "LEGOS" is the natural plural, since that's the only one they bother to correct. So, in formal usage, both "Lego" and "Legos" are wrong. To me, that means people shouldn't make such a big deal about it in informal use!
