"I never go anywhere."
Translation:Eu nunca vou a lugar nenhum.
Algum and nenhum are both quantifications, where algum is positive and nenhum is negative. They don't always have one English translation although most of the time algum is "some" and nenhum is "none". Eu vou para a festa com alguns amigos (I go to the party with some friends - quantifiably positive). Eu fui para a festa com nenhuns amigos (I went to the party with no friends - quantifiably negative). Tense doesn't matter in this case I just wrote the second phrase in the past randomly
