Personification brings an abstract and conceptual thought more real and relatable. Wisdom is often personified as a woman in Proverbs as a means of illustration, which I mentioned in an earlier post and in my study guide for Proverbs.
Personification makes things more personal, like BB King's guitar named Lucille and Willie Nelson's guitar Trigger. Ships and cars are often referred to as if feminine and sometimes characters or caricatures serve to personalize an attitude like Dickens' Scrooge and Dr. Seuss' Grinch.
