词源小故事

作为目前世界上使用最广泛的一种人工语言，世界语Esperanto这个单词来自创造了世界语的波兰眼科医生柴门霍夫第一本书的笔名“Doktoro Esperanto（希望博士）”，Esperanto这个单词的字面意思是“He who hopes”，来自拉丁词根sper=hope希望。柴门霍夫出生时，波兰正受着俄罗斯的统治，他的母语是俄语和依地语，但他也精通波兰语和德语，他又曾学习了法语、拉丁语、希腊语、英语和希伯来语，同时也研究意大利语、西班牙语和立陶宛语。他出生的小镇有三个民族的人居住：波兰人、犹太人和白俄罗斯人。由于语言、宗教信仰不同，所以他们经常互相产生偏见和仇恨。柴门霍夫认为语言不同使人们不能互相交流是产生偏见的主要原因，所以当他在华沙上中学时，他就试图创造一种人类共同的语言，以使不同民族的人可以好好地互相交流。
