《朗氏对外德语大词典》收录词目约66000条，选词广泛，此外反映时代发展、社会变革、青年行为等等的新词语、新概念在词典中也有较明显的体现。尤其值得一提的是，该词典从教学法角度考虑对30000余条复合词的精选安插，对主要构词要素的立目释义独具匠心的编排，能激发读者扩充词汇的求知欲望和举一反三的构词能力，同时也给读者敞开了一扇去感受和探索德语词库的浩瀚和深湛的大门。学会正确遣词造句是每个学习外语的人所期望的。本词曲对动词、名词、形容词刻意设计的结构格式，2100余条语法疑难的说明，对介词的支配关系和形容词的句法功能等等的点拨，确实起到了教与学各得其所的作用。

"Roget's Thesaurus" is the world's most famous and trusted word-finder. First published in 1852, it has now sold over 32 million copies worldwide and has become the indispensable desk companion for generations of speakers and writers of English. Unlike most other thesauruses, it groups words thematically rather than in a straight A-Z sequence, thus offering the writer and speaker a much more creative and subtle means of finding new ways to express their thoughts: it is essential for anyone who wants to improve their command, creative use and enjoyment of English, and is perfect for composing speeches, or for writing all manner of prose and poetry. It remains, definitively, a writer's best friend. "Roget's Thesaurus" is part of the Penguin Reference Library and draws on over 70 years of experience in bringing reliable, useful and clear information to millions of readers around the world - making knowledge everybody's property.
