  • To introduce a long quotation

  • To introduce a list


  • To separate and add emphasis to an extra comment in a sentence

  • To show a range (numbers 1 – 64)


  • To show possession (Herman’s hermit, the girls’ gym class)

  • To substitute for missing numerals (’07)

  • To substitute for missing letters in contractions (isn’t, what’s and he’s)


  • To divide words or syllables at the end of a line

  • To link two descriptions of one word (second-string violinist)

  • To attach prefixes to words that start with capital letters (anti-Nazi)

Add interest to your writing with these tricks:

  • Start with a description (Dangling over the cliff, Martha considered her options)

  • Combine sentences by inserting one idea into another (Martha, who hated heights, looked at the ground)

  • Occasionally reverse the usual subject-verb order (Onto the valley floor thumped Martha)

  • Cut unnecessary words (The mountain was 3,000 feet high in altitude. No need for in altitude.)

  • Look for strong verbs (Strolled or rushed instead of went, for example)
