William Wordsworth`s "Lucy poems" are characterized by his traumatic loss of Lucy and ambiguous recovery from it. They inform us chiefly of his bitterness at having lost the girl and his failure of detaching himself from his loss of her. When the speaker cries "The difference to me" in "She Dwelt among the Untrodden Ways", for example, he admits that she may be dead and yet expresses his doubts about the reality of his loss. The moment the speaker in Lucy poems faces with traumatic event, he neither hears nor sees: he cries "If Lucy should be dead" in "Strange Fits of Passion Have I Known" as if he has not realized her death. The traumatic scene or thought in Lucy poems cannot be a possessed knowledge in the speaker; it rather produces a profound uncertainty or incomprehensibility. Because of the lack of the system of comprehension, the trauma returns continually to be connected with other images and words. The impact of a trauma is tied to the elapsed time between the unperceived event and the first appearance of the symptoms. In "A Slumber did My Spirit Seal," for example, the speaker is unable to face her death and unable to forget her. The Lucy poems` double structure of incomprehensibility and inherent latency makes the reading process complex and difficult. They demonstrate the structure of trauma which is symptom of the lack of comprehension as well as the cause of repetition.
