单词“isn't”是英语中常见的否定缩写形式,全称为“is not”,用于表达对主语状态、属性或行为的否定。其语法结构通常为“主语 + isn't + 表语/现在分词/介词短语”,例如:“The weather isn't good today”(今天天气不好)。根据剑桥英语词典的解释,此类缩写常见于口语和非正式书面语中,能够简化表达并增强语言流畅性。
在语言学层面,“isn't”属于系动词否定形式,仅适用于第三人称单数主语(如he, she, it或单数名词)。例如:“This answer isn't correct”(这个答案不正确)。牛津英语语法指南指出,此类缩写在标准英语语法中被广泛接受,但在正式文书(如学术论文、法律文件)中建议使用完整形式“is not”以保持严谨性。
需注意避免以下两种常见错误:
此外,“isn't”与其他否定缩写(如don't, can't)构成英语否定体系的核心。根据柯林斯词典的语料库研究,这类缩写在日常对话中的使用频率比完整形式高63%,体现了英语语法经济性原则。
