ex-girlfriend翻译为前任女友。ex最为前缀它的全称是什么？还有co-write是什么意思？

co-表示“共同”、“和”的前缀 1．Co- co-exist(共存)，co-operate（合作），co-education（男女同校）
co-write 就是共同写作

ex就是表示前。。。没有全称

ex: In social relationships, an ex (plural exes) is someone with whom a person was once associated. As a prefix, ex- can refer to a variety of different relationships; for example, one might refer to a music group's ex-guitarist, or someone's ex-friend. When used alone, ex is assumed to refer to a former sexual or romantic partner, especially a former spouse. This often has a derogatory tinge; some French media take advantage of this connotation by calling French ex-president Valéry Giscard d'Estaing simply the Ex.
co-write 共同作品

ex全称是ex-,注意后面有个- （不要奇怪）
在词典里面找ex-可以查到，其为副词，意为从前的，以前的
co-的意思为联合，一起。 co-write：一起写的

所有的前缀都没有全称，包括ex。

掌握读法就 可以了。

ex-在英语里指是个前缀,并不是什么单词的缩写
co-write 就是说共同写作, 也就是说这人不是单独创作, 而是跟别人一起写的

ex是一个前缀，无所谓什么全称。就像unhappy里面的前缀un-也没有全写的。
co-write 合著
