"hasn't"是英语中"has not"的缩写形式，属于现在完成时的否定结构，主要用于第三人称单数主语（he/she/it）。该缩写在口语和非正式书面语中使用频率较高，具备以下语言特征：
语法构成 由助动词"has"与否定副词"not"组合而成，遵循英语否定句的常规缩写规则。根据《牛津英语词典》的解释，这种否定缩写形式最早可追溯至17世纪英语的语法演变过程。
时态应用 专门用于现在完成时态，表示从过去持续到现在未完成的动作或状态。例如剑桥英语语料库收录的典型例句："She hasn't finished the report yet"（她尚未完成报告）。
发音特点 在美式英语中常发为[ˈhæzənt]，英式英语则为[ˈhæzənt]，尾音/t/可能出现弱化现象。语言学家David Crystal在《英语语音模式》中指出，这种发音弱化现象与语速和语境密切相关。
使用限制 不可用于正式文书或强调否定语气的场合。根据《朗文英语语法指南》，当需要特别强调否定含义时，应使用完整形式"has not"，例如："I assure you he has NOT stolen the money"（强调否定）。
单词解释：hasn't
