词根
"Beforehand" 是由 "before" （在之前）和 "hand" （手）两个词组成，"hand" 在这里是一个表示状态或位置的词。 这个单词本身就具有完整的意思，因此我们并不能从词根中推导出其他单词。
释义
adv. 事先；预先 adj. 提前的；预先准备好的
例句

强化记忆
一种记忆的方式是将 "beforehand" 拆分为 "before" 和 "hand"，并以此形象化为在事情到来之前已经摆在手上，意即提前准备好。"Beforehand" 这个词语起源于中古英语的 "biforen hand" ，在早期英语中，"hand" 有时被用来表示位置或状态。于是“biforen hand”被直译为在手之前，即事先，提前。
