The poem tells the story of Mariana, who is left alone in her home pining for her lover who never returns. Tennyson uses language features such as synonyms showing decay and stasis, spondee with long vowels lengthening lines, and a lack of verbs and voice besides the narrator and Mariana. The structure includes a refrain, epizeuxis or repetition, and collapsing rhyme patterns that fold lines in. These formal elements shape how the lonely, stagnant story of Mariana is conveyed.
