Theory:

Personification is a figure of speech, a poetic device in which human attributes are given to animals, non-living things or ideas. The objects speak/behave like humans, with human emotions in such cases.
Example:
Personifying animals:
  1. The cat asked the mouse for a dinner treat.
  2. The dog asked his master to let him inside.
Personifying ideas:
  1. Love is blind.
  2. His anger oozed out in his words.
Personifying non-living things:
  1. The popcorn popped out of the bowl immediately in the oven.
  2. The sun shined and smiled upon us, early in the morning.
Uses of personification:
  1. When human qualities are given to objects, the writer/poet can convey the meaning easily.
  2. The understanding of the idea is made easier when objects are personified.
  3. It helps to build a character around the object.
  4. Makes the text/poetry more interesting and fun to read.
  5. Literal meanings are to be ignored in such cases.
Personification used in the poem "Mystery of the Talking Fan":
 
The entire poem is a personification as the poet mentions a non -iving thing, the ceiling fan as something that has life. She says that the fan talks, runs, communicates etc. The phrase "Talking Fan" from the title is itself a personification. The poet refers to the fan with the third person pronoun "he", throughout the poem. The poem refers to the fan as having emotions and feelings.
