Extra Info: Brackets, Dashes, and Commas W1-mt_m3-eXac3aP-s1

  1. next to the bank · The extra info sits inside the brackets: 'next to the bank'. Lift it out and the sentence still works.
  2. Our cat — the fluffy grey one — sleeps all day. · An aside marked with dashes needs two of them, one to open and one to close.
  3. Our teacher, who cycles to school, knows every shortcut. · A comma aside needs a matching pair: one comma before the extra info and one comma after it.
  4. the one from Peru · The aside sits between the matching dashes: 'the one from Peru'. It adds extra detail about the aunt.
  5. It is extra info the sentence does not need · Brackets hold extra info. Cover 'who loves dinosaurs' and the sentence still works: 'My cousin showed me a fossil.'
  6. True · The two marks around an aside must match. A dash opens it, so a dash has to close it.
  7. Commas · Commas sit right in the middle: more noticeable than brackets, gentler than dashes.
  8. False · Brackets are the quietest marks and dashes are the loudest, so brackets make extra info stand out less, not more.
  9. The cake (chocolate) baked for an hour. · Only the middle sentence brackets a truly extra bit. Lifting out 'chocolate' leaves 'The cake baked for an hour.'
  10. Swap the brackets for dashes · Dashes give an aside the most emphasis, so swapping the brackets for dashes makes it stand out more.
