易错句子I got permanent at the salon last week.

permanent 作名词表示“烫发”时是可数名词,单数形式前必须加不定冠词 a;汉语没有冠词系统,学习者常直接漏掉,写成 got permanent。

易错句子She permanented her hair yesterday.
正确表达She got a permanent yesterday.
permanent 只有名词词性,不能像动词一样加 -ed 使用;汉语“烫发”是动宾短语,容易被直接套成英语动词。英语应说 get/have a permanent,或 get one's hair permed。

易错句子She had a permanent hair before the wedding.
正确表达She had a permanent before the wedding.
名词 permanent 本身已表示“烫发”这一处理,后面不再接 hair;若接 hair,permanent 会被读成形容词“永久的”,变成“永久的头发”,与原意不符。
perm 是 permanent 作名词时最常用的口语缩略形式,两者指同一种化学烫发;英式英语里 permanent 作名词偏正式、略显老派,日常多说 perm,美式英语同样以 perm 为主。区别在于:perm 还能作动词(to perm one's hair),而 permanent 作名词只指“一次烫发”这件事本身;另外 permanent 更常见的是形容词“永久的”,那种用法不能换成 perm。
permanence 是不可数名词,说的是“持久不变”这一抽象性质(如 the permanence of the effect);permanent 作名词是可数名词,指具体的一次烫发(two permanents)。一个讲性质、一个讲事物,拼写又相近,最容易混用,但两者不能互换。
