In this poem the poet is speaking with his own voice about a girl, Lucy, who lived in a solitary place. Very a few people knew and appreciated her but the poet did it.
As for as the setting is concerned, the time isn't specified but the place is (line 2: "besides the springs of Dove") .

The stress pattern is regular in the first two stanzas where the poet describes Lucy, it changes in the third stanza where he talks about Lucy's death and the effects of this event on himself.

The rhyme scheme is "abab cdcd efef" so it's regular and it's mostly based on perfect rhyme with the exception of the consonance in lines 5-7.

The poem is divided into 3 stanzas of 4 lines each. The firs stanza describes the setting and the character of the poem who at the beginning it isn't specified ("she" line 1 in key position at the beginning of the stanza) another word in a key position is "love" (line4) at the end of the poem where the poet express his feelings.

The second stanza presents the description of Lucy through a metaphor (lines 5-6) and a simile (lines 7-8) the image of the violet communicates a sense of delicacy, as well as it underlines the fragrance of the flower transferring these quality to the girl. The mossy stone hides the violet as the solitary place hides the qualities of Lucy, as it is specified in the line 9 ("she dwelt unknown"). Then the poet compares Lucy to a precious solitary star which is shinning on the sky. The image of the star conveys the ideal the ideal of the importance of the girl as well as the sense of brightness as if as if the presence of Lucy made the poet's life shine.

The last stanza opens again with word "she" (line 9) and closes with the word "me" (line 12) to point out that the attention of the poet shift from the setting and description on the girl to the poet's feelings. In this stanza the poet calls the girl by her name revealing it, making her more real and increasing the level of familiarity. Through the last exclamation it's possible to understand the importance of Lucy for the poet and he's suffering for her death.

In conclusion it is possible to say the language used by the poet is quite simple in the choice of words but rich on the sound and figurative level.
