Native-speaker    

操本族语者

A term used in linguistics to refer to someone for whom a particular language is a first language or mother-tongue. The implication is that this native language, having been acquired naturally during childhood, is the one about which a speaker will have the most reliable intuitions, and whose judgements about the way the language is used can therefore be trusted.

语言学用语，指将某种语言作为“本族语”（也叫“第一语言”“母语”）的人。由于这种语言是儿童时期自然习得的，因此说话人对它的直觉最为可靠，因而他对这种语言使用方式的判断是可信的。
