I wondered lonely as a cloud

This poem is about a lonely and probably sad person who while passing by a lake comes across a field full of daffodils waving and dancing in the breeze. Seeing the daffodils dance filled the person's heart with joy and from then on whenever he felt sad he started thinking of the dancing daffodils which made him feel better.

The speaker uses simile when he says that he is wandering lonely as a cloud and then again when he says the daffodils are dancing like stars in the milky way. In the second line we see apostrophe in the word ''O'er''. Also by saying ''dancing daffodils'' the speaker is giving them a human trait and therefore we have personification in the poem as well.
