How does onomatopoeia influence the passage from “song of myself”

Read the passage from a raisin in the sun. beneatha (laughingly noticing what her mother is doing): mama, what are you doing? mama: fixing my plant so it won't get hurt none on the way . . beneatha: mama, you going to take that to the new house? mama: un-huh— beneatha: that raggedy-looking old thing? mama (stopping and looking at her): it expresses me! ruth (with delight, to beneatha): so there, miss thing! how would the tone change if the word hideous replaced the word raggedy? beneatha would be showing anger instead of expressing her sadness about the plant. beneatha would be telling a hilarious joke instead of making a mildly humorous comment. beneatha would be telling the truth to her mother instead of sparing her feelings. beneatha would be harshly criticizing her mother instead of gently teasing her.
