sedentary = sed(坐) + ent(…的) + ary(…的) = 坐着的，固定不动的
sedmentary = sed(坐) + ment(表名词) + ary(…的) = 坐到底下的→沉积的，沉淀的
detritmental = de(变坏) + trit(摩擦) + ment(结果) + al(...的) = 摩擦坏了的→有害的
disillusionment = dis(相反) + il(进入) + lus(玩) + ion(表名词) + ment(结果) = 被幻觉玩弄而崩溃→幻灭
aberration = ab(离开) + err(漫游) + ation(表结果) = 离开常规去漫游→偏差
acceleration = ac(加强) + celer(快) + ation(表结果) = n.加快，加速
坐下→沉积物，沉淀物
sedimentation
常考释义
After Hutton, geologists tried to determine rates of sedimentation so as to estimate the age of Earth from the total length of the sedimentary or stratigraphic record.
在Hutton之后，地质学家试图确定沉积过程的速率，因为他们想通过沉积记录或者地层记录的整体长度来估计地球的年龄。
