It looks like your message might be incomplete. If you intended to ask about the meaning of a phrase, a specific word, or something else starting with “what does,” please share the full question or context and I’ll address it directly. If you were asking about the phrase “what does,” here are a few common ways it’s used:

• Asking for the meaning or function of something (e.g., “What does this symbol mean?”).
• In grammar, introducing indirect questions (e.g., “I’m not sure what does this refer to”—the correct form would be “what this refers to”).
• In explanations, it can lead to definitions, examples, or clarifications (e.g., “What does ‘empathy’ mean?”).

Please provide the complete query or any specific topic you're curious about, and I’ll give a clear, precise explanation.
