second language和foreign language 的区别？

Question

second language和foreign language 的区别？我能不能理解为second language就像英语在很多欧洲国家被广泛应用，而英语在中国是foreign language，只是在教室里学学，出来这个环境大家都很少用。那个高手来解答一下，谢谢。

Answer 1

还是有区别的，second language是第二语言，foreign language是外语（非母语）。一个人的foreign language可以有好几种，second language只有一个

every language used by a foreign nation which is different from your native language can be called a foreign language.

however,the notion of a "second language" can be explained like this:

this is a language u also have a good command of.in offical or common accasions,u may use your first language as first prioriry usually,but when first language can't be used to communicate with each other,the second language is up to.

Answer 2

前者为第二外语，就专门指除了第一外语的第二门语言，就一门！！
后者为外语总称！包括除母语外的所有语言，很多们！

Answer 3

first
language
就是母语
（家里说的语言）
second
language
就像是学校里学的
（就是日常生活会接触道的语言）
foreign
language
则是一门完全陌生的语言比如说法语。。。
