n.深奧；難懂

Classical Chinese poetry is characterized by its terseness in language, abstruseness in meaning, richness in imagery, sharpness in emotion, and distinctiveness in rhyme and rhythm. 中國古典詩歌以其精煉的語言，深刻的內(nèi)容，豐富的意象，強烈的感情，以及鮮明的節(jié)奏和韻律吸引了無數(shù)中外讀者。

and the abstruseness secret who can realize? 那深奧的秘密又有誰能領(lǐng)悟得出？

As the "a" circle keep expanding, people marvel at the abstruseness and misteries of nature; a圈向外延展著，人類一路驚嘆著自然之深邃神秘不可知；

in so far as the books are of recognized everlasting value, regardless the abstruseness. 從教法說，就是要他多念多反覆乃至于會背誦！
