"brother"是英语中表示兄弟关系的核心词汇，其含义在不同语境中具有多层次延伸。根据《牛津英语词典》，该词最基础的含义指"同父母或同父/母的男性子嗣"，例如："My younger brother just started college"（我的弟弟刚上大学）。在宗教领域，《大英百科全书》记载该词可特指"修道院中的男性成员"，如中世纪修士互称"brother"体现宗教团体的平等性。
该词的社会学含义在《剑桥词典》中被拓展为"具有共同目标的团体成员"，例如工会运动中"brotherhood"（兄弟会）的概念。现代语言学研究发现（《美国俚语词典》，在非裔美国人社区中，"brother"已成为表达文化认同的称呼方式，如"Hey brother, what's up?"既可能指血缘兄弟，也可能表示社区同胞。
词源学研究显示（《在线词源词典》，"brother"源于原始日耳曼语*brōþēr，与拉丁语frater、梵语bhrātar同源，这种跨语系关联印证了人类亲属关系的普遍性认知。在法律语境中，《布莱克法律词典》特别注明该词包含"同父母男性子嗣"和"同父异母/同母异父男性子嗣"两种法定亲属关系。
通过以上解析，“brother”不仅是一个家庭称谓，更承载着友情、团结和文化象征的多重意义。如需更具体的短语或文化案例，可参考来源。
