|Occupation||Correctional grammar robot|
|Relatives||Inventor: Lisa Simpson|
|First Appearance||Trilogy of Error|
|Voiced By||Hank Azaria|
Linguo was a grammar-correcting robot created by Lisa for the science fair. Whenever Linguo detects a grammatical error it responds with the correct answer. Homer nearly destroys Linguo when he mistakes it for a toy robot and gives it beer. Lisa fixes Linguo, but he is later destroyed when members of the Springfield Mafia make numerous grammatical errors in his presence, causing an overload of Linguo's circuits. Linguo's last words are voiced in correction of Homer: "Linguo is dead."
Ironically despite being designed to correct grammer, Linguo was capable of using incorrect grammer himself. When Lisa pointed out that him saying "Sentence fragment" to point out her use of one was itself a sentence fragment, it looked around embarressed before powering down.
