Human: I have a question about the word Lego (toy). When I say Lego, you understand that I mean the toy, right? Assistant: 
Yes, I do.  Lego is a trademarked name for a toy.  The word Lego is a portmanteau of the Danish words “leg godt” which means “play well”.  The Lego toy is a building block toy that was invented in the late 1940s by Ole Kirk Christiansen.  The toy is made of interlocking plastic bricks, and is designed to be used by children to build various structures.  The toy is popular in many countries around the world, and is often used in educational settings.
