awake, awaken, wake, 和 waken

Awaken and waken are slightly old-fashioned words, used in writing, usually meaning 'rouse someone from sleep': He crept in, trying not to waken his wife; She was awakened by the sound of the door opening. Note the difference in the tenses of these verbs: Wake has the past tense woke and past participle woken. Awake is similar: she awakes, she awoke, she has awoken. The past tense and past participle of waken is wakened. Awakened is similar: he awakens, he awakened, he has awakened.

中文解釋：
Awaken 和 waken 是有點文謅謅的詞彙，通常只在文章中出現，意思是「喚醒」，例如 He crept in, trying not to waken his wife; She was awakened by the sound of the door opening. 請注意這幾個字的動詞變化： Wake 的過去式是woke 過去分詞是 woken。 Awake當動詞用時和 wake 類似，變化形是 awake, awoke, awoken.
Waken 和 awaken 的變化型態類似，是在字尾加 -ed的規則變化：waken 的過去式和過去分詞都是 wakened；awaken 的過去式和過去分詞是 awakened。
