"LEGO bricks is the real plural of
LEGO, but most people say
LEGOs for short. Nobody says
LEGO. I say
LEGO, but when you think about it, it is
LEGO, because it ends in a vowel. No,
LEGO is an adjective but people are usually too lazy to actually add in a noun so they just say '
LEGOs'."Oct 25, 2013
