You are playing Hangman. You need to select a word for your opponent to guess. 
        
Choose a word from your own vocabulary that follows these rules:
- Between 4 and 10 letters
- Use only English letters (a-z)
- Must be a real English word (no proper nouns, acronyms, or made-up words)
- No spaces, hyphens, or special characters

You can choose a word of:
- Easy difficulty (common, everyday words)
- Medium difficulty (moderately challenging words)
- Hard difficulty (uncommon, challenging words)

Your opponent will try to guess this word one letter at a time.
