Yep - the plural of Lego is ...................Lego![]()
Actually, we're both wrong.
I was looking at their site and everytime they talk about their products or company or divisions, they always put something after LEGO and make that plural.
So I did a quick search and here is what I found:
Which is correct as the plural of LEGO: 'Lego' or 'Legos'? Neither, actually. The word 'LEGO', when used as a noun, should only refer to the company that makes the product. Otherwise 'LEGO' is supposed to be used as an adjective. Thus, when referring to the pieces, neither 'lego' nor 'legos' is correct... rather one should say: 'LEGO bricks' or 'LEGO pieces' or whatever (using LEGO as an adjective -- and one should really capitalize all of the letters, and put the little 'circle-R' symbol after it (®)). This is all a matter of protecting the trademark of 'LEGO' for the company (using it otherwise degenerates the strength of the trademark).
