He does not use fancy language to express his love and appreciation.
Although the rap is like telling a story, Tupac uses end rhymes for a few sentences, which shows his poetic side with writing his raps. He presents the past and moves in to his present life, which is when he thanks God for how much love his mother gave him. The structure of the rap is generally chronological because he starts off by explaining how he was a teenager, but he mentions "Your are appreciated" in the beginning and after every verse.
He uses both a first person and third person point of view because he explains certain situation regarding his mother but also raps about his own actions and emotions by using "I". This tone is what makes many people cry when they first listen to this rap. The tone of the song is appreciating, understanding since he realizes his mother's care, loving, sad since he explains terrible struggles, and immensely emotional. He even explains that he was in jail with his mother and that she still tried to do the best she could to raise a man like him. The rap makes it clear that he has become who he is because of his mother and he is truly thankful of it. The rap is primarily focused on the appreciation he has for how his mother raised him even when his father passed away and through all the financial struggles they went through. He tells the story of him growing up with his mother and how much he appreciates what she has done for him. "Dear Mama" is a personal rap by Tupac Shakur about his mother.
