1、Latin surdus "deaf, unheard, silent, mute". => surd-: deaf, unheard, silent, mute.
2、surd- => surd: irrational.
3、咱们汉语里有表达这种关联的形象的成语：掩耳盗铃、装聋作哑、充耳不闻；这些行为是不是都非常的荒唐、荒谬、无理取闹啊！因此，由词根含义转变到、引申到单词含义自然就水到渠成了。
4、ab- "away, off; 由于该前缀的这层含义，在这里添加在surd之前更加强了surd的含义，为什么呢？想一想充耳不闻、装聋作哑地走开(away, off)，就明白了！" + surd- / surd + -ly => absurdly.
5、In surd, the mathematical sense is from the use of Latin surdus to translate Arabic (jadhr) asamm "deaf (root)," itself a loan-translation of Greek alogos, literally "speechless, without reason".
6、In French, sourd remains the principal word for "deaf".
