“兄弟姊妹”是汉语里常用的亲属称谓,产生较早,其中“兄、妹”在甲骨文时期就产生了。这四个字在文言文中既可以单独使用,也可以构成复合词“兄弟”“姊妹”。作为汉语的基本词语,它们虽然具有很大的稳固性,但历经三千多年发展,其词义也产生了一些变化。 “Brothers and sisters” is a commonly used relative term in Chinese, which originated earlier. Among them, “brothers and sisters” were created during the Oracle period. These four words can be used alone or in compound words “brothers” and “sisters”. As basic words of Chinese, although they are very solid, they have evolved over 3,000 years, and their meaning has also changed.
