In the arts, personification means representing a non-human thing as if it were human. Personification gives human traits and qualities, such as emotions, desires, sensations, gestures and speech, often by way of a metaphor.
Personification is much used in visual arts. Examples in writing are "the leaves waved in the wind", "the ocean heaved a sigh" or "the Sun smiled at us". In easy language personification is just giving an example of a living being for a non-living thing. "The wind shouted". In these examples, the nonhuman subjects are given human characteristics.
