* The Fury: This is the nickname Bruno uses for the man he sees through his window, whom his family calls "Father". This nickname suggests fear and a sense of power the Fury holds.
* The Commandant: This is the formal term used by Bruno's family and others. It highlights the man's position of authority and control.
* "He's a bad man, that's what he is.": This is Bruno's simple but powerful statement about the Fury, revealing his own understanding of the man's nature.
Bruno's limited vocabulary and his childlike perspective prevent him from providing a detailed description of the Fury. Instead, his words reflect his own feelings of confusion, fear, and growing awareness of the man's dangerous power.
It's important to note that the novel is told from Bruno's innocent and naive point of view, offering only a glimpse into the monstrous character of the Fury. The lack of a direct description adds to the ambiguity and horror of the situation, emphasizing the power of the unspoken and the vulnerability of innocence in the face of evil.
