Specific Improvements Made

Swiss German Vocabulary Additions

Spelling Corrections (Swiss vs. German Standard)

Word Selection Improvements

Regional Dialect Considerations

• Vocabulary reflects Swiss usage, not German or Austrian variants
• Special attention to Swiss-German loanwords and regionalisms

• Manual typing test performed to verify readability
