Beginning of consciousness?

SELF

Think of the word that defines your own identity before anything else exists.

The clue plays on the idea of "consciousness" as both awareness and the philosophical concept of the self. "Beginning" hints at the first letters of the words, but here it’s a misdirection—the answer is simply "SELF," the core of personal identity. The question mark signals wordplay, suggesting you think beyond literal definitions to the essence of what makes someone conscious of their own existence.
