Answer:
The theme of "Mother to Son" is the struggle and perseverance through difficult times. The mother uses figurative language to convey this theme, such as when she says "Life for me ain't been no crystal stair." This metaphor compares life to a staircase that is not smooth and easy to climb, but instead has "tacks," "splinters," and "boards torn up." The mother also uses personification when she says she has been "climbin'" and "reachin' landin's," giving life-like qualities to the act of climbing a staircase. These examples of figurative language relate to the theme by emphasizing the hardships and obstacles that the mother has faced, but also highlighting her determination to keep climbing and not give up.
