Despite its title, the word "your" is not heard in the song until its reprise. The track's introduction is preceded by a spoken monologue. According to Lindsey Romain of "Marie Claire", Ariel begins the ballad by "acknowledging her privilege as a princess ('Wouldn't you think I'm the girl who has everything?')" before admitting to wanting more. Similarly, KQED contributor Emmanuel Hapsis wrote that the character "laments that, despite a life of privilege and spoils, there's still a deep loneliness inside her". Beginning "Look at this stuff, isn't it neat? Wouldn't you think my collection's complete? Wouldn't you think I'm the girl/The girl who has everything?", "Part of Your World" is "a plea for a life of discovery" and "inquisitiveness" as opposed to love, using "nonsensical expressions" such as "gadgets", "gizmos", "whosits" and "whatsits" in lieu of various human artifacts.
