Large Numbers (e.g., 170, 700):

Etymology and Evolution: Why "Seventy"?
The word seventy has deep roots in the English language:

- Incorrect Spelling: "Seventy" is not "seventy" (missing 'e'), "seventy" (extra 'e'), or "seventy" (missing 't').
- Misplaced Hyphens: Hyphenate only compound numbers from twenty-one to ninety-nine. "Seventy" alone stands alone; "seventy-one" is hyphenated.
- Ordinal Confusion: Remember "seventieth" (70th), not "seventyeth" or "seventyth".
- Inconsistent Capitalization: Only capitalize "seventy" if it starts a sentence or is part of a proper noun (e.g., "Seventy Acre Park").
