A purely American usage of the word LEGO as a plural (more than
one). This is not considered a word in any other part of the globe. LEGO is both singular and plural. The same way
moose, deer, gymnastics, furniture, baggage are both singular and plural. LEGO is a brand
name. There are LEGO bricks, LEGO tiles, LEGO plates, LEGO tires, LEGO
books, LEGO competitions, LEGO theme parks, and countless other LEGO elements, but there are no LEGOS. EVER.
The closest would be a possessive form, as is LEGO's corporate offices or LEGO's employees, or LEGO's logo.
LEGO are manufactured in Denmark, Hungary,
Mexico and
China. Of the
400 Billion LEGO elements there are exactly zero LEGOS.
