Punctuation is sub-category of Grammar

Note:

  • punctuation is used to set rules for recreating in writing human speech
    • such as hard pauses (periods, semicolons, colons, dashes and parentheses) and soft pauses (commas)
  • however, punctuation enables writing to go beyond verbal communication for complex expression and meaning

Colon

  • must be preceded by an independent clause
  • can be followed by anything
    • except a conjunction
    • the reason is that conjunctions and colons do the same thing

comma

  • used to create a pause
  • used to separate ideas
  • the five uses of a comma:
    • joins independent clauses
    • joins phrases or dependent clauses with an independent clause
    • creates lists
    • parenthetical or bracketed information
  • sometimes called "interrupters"
    • for lists and parenthetical uses

for lists

  • = separates nouns, verbs and series of clauses
  • the serial comma = comma following the 2nd to last word in a list and before the conjunction:
    • ex.: "one, two, or three bananas"
      • known as the "Oxford comma"
      • = the British convention (rule or typical use) is to place a comma after the 2nd to last word in a list
    • vs.: "one, two or three bananas"
      • both forms are correct
      • generally, American usage is to use the "serial comma" that comes before the conjunction
