Key ideas in Semicolons and Then vs. Than
- 'Than' is required when weighing two items or people against each other
- Comparative adjectives ending in -er (like taller, bigger, faster) always pair with 'than', never 'then'
- 'Then' moves a story or timeline forward to the next chronological event
- Sequence markers describing 'what happens next' require 'then' instead of 'than'
- The letter 'e' links 'then' directly to 'time'
- The letter 'a' links 'than' directly to 'comparison'
- Substituting 'next' or 'after that' serves as an immediate check for 'then'
- If replacing the word with 'next' produces nonsense (like 'taller next him'), the correct word must be 'than'
- Fixed preference phrases like 'rather than' and 'other than' always take 'than'
- Expressions evaluating quality such as 'better than' or 'worse than' are comparisons that never take 'then'
- Both parts before and after a semicolon must be capable of standing alone as complete sentences
- A dependent clause starting with words like 'because' or 'before' cannot stand alone after or before a semicolon
- A semicolon has the exact same structural boundary requirements as a period
- If a period creates a sentence fragment on either side, the semicolon is invalid
- A comma by itself cannot join two complete sentences (a comma splice)
- A semicolon has the grammatical strength to join two complete thoughts without words like 'and' or 'but'
