Final answer:
The word 'designated' in the poem highlights the speaker's empowerment in choosing their identity and supports the theme of self-belief.
Step-by-step explanation:
The use of the word designated in the poem supports the theme that believing in yourself is possible even if others don't believe in you. This is because the word designated implies that the speaker has taken the power to define their own identity, moving from being a 'nobody' to claiming the title of 'Somebody'. The act of self-designation reflects the speaker's inner strength and conviction in their self-worth regardless of others' dismissive attitudes. It is a potent declaration of self-empowerment and transformation, epitomizing the crux of the poem's message about self-belief.
