Codsworth, the pre-war Mr. Handy robot you meet at the beginning of the game, will be your faithful butler companion in the bleak Commonwealth. What's more, Codsworth can speak and even address you by name, provided he can pronounce it. This way, you can personalize your gaming experience and get more out of the gameplay. However, the robot's vocabulary is limited, so if you want it to stop calling you Sir or Ma'am, you can check out our Fallout 4 Codsworth names list to choose the one that suits you and that it can pronounce.
