Starting from the title the pronoun "I" and the adverb "lonely" are the words that immediately strike the attention of the reader.

The speaking voice is alone and he goes without a definite direction;  his condition of going nowhere is compared to the condition of the clouds , which are moved by the wind. The comparison is made up by a simile ("as a cloud")

The poem is organized into four stanzas of six lines each.

In the first stanza the speaking voice is walking without a definite direction when he sees "a crowd" of daffodils waving in the breeze.

The poet is providing the reader with a personal experience he had. The setting is the countryside , which is typical of Romantic poetry because country and nature become the ideal setting for man's inspiration.

The "golden daffodils" are what captures the attention of the speaking voice, they are described as a "crowd", a "host", they are "fluttering and dancing in the breeze". The poet describes the flowers as if they were living people, using personification.

It appears clearly the contrast between the flowers that are so many and the poet who is alone, solitude,"lonely".

The adjective golden conveys the idea of something precious, which has a value.

The image that comes to surface is positive, also thanks to the alliterations of the open vowel sounds  /a/ and /e/ which creates an eco-effect.

Moreover the speaking voice appeals to senses, therefore the language used is the language of sense impression; as a matter of fact romantic poetry expresses the subjective emotional reaction of the speaking voice in front of a situation.

In the second stanza the poet continues to describe the flowers, insisting on their being so many; he uses expressions like "continuos", "never - ending line", "ten-thousend" (hyperbolic use of the language; moreover in the line "ten-thousend saw I at a glance" the poet changes the ordinary word-order to underline the high number of the flowers).

The daffodils seem to be animated, they create a lot of light around them and they "dance"; Romantic poetry animate nature.

There is again a simile: "as the stars that shine"; the line "they stretched in a never ending line" conveys to the reader a sense of vastitude, thank to the alliteration of the sound /e/.

In the third stanza the speaking voice goes on describing the moving of the flowers but he also expresses his total emotional involvement in front  of the scene; "a poet could not but be gay", he couldn't do anything else.

His attention is totally caught by the moving of the flowers and as a consequence he "little thought"; he only thinks about the wealth that the scene has brought him; a strong alliteration of the sound /w/ ("what", "wealth", "show") highlights the subjective reaction of the poet who is observing the scene.

The flowers, after being described as a "crowd", a "host" are now called "jocund company", again emphasizing the number of them and personifying them.

The anaphoric use of the language, "I gazed - and gazed" (to gaze means to look intently and steadily), underlines the visual aspect and on the sense of the sight.

In the last stanza the reader can see of the poem is born: the poet was alone, on his couch, he was remembering the flowers, "they flash upon that inward eye", which is imagination (imagination is the most important word in Romanticism).

Remembering the scene provides the poet the same pleasure he had while he was really looking at the flowers.

The poem is written in the simple past because Romantic poetry is always the record of the memory.
