When to Use Hyphens

A hyphen should be used to signal:

  • A half finished word
  • An abrupt end to a sentence which then is not continued

Example: "For examp-"

#

When NOT to Use Hyphens

Hyphens should not be used:

  • Parenthetically (use dashes or commas instead)
  • In cases where the speaker carries on their thoughts

They are reserved for abrupt end to words or sentences.

#

Key Distinctions

##

Hyphen (-) vs Dash (–)

  • Hyphen (-): For cut-off words or compound words
  • Dash (–): For parenthetical thoughts or longer pauses

#

Examples

Correct hyphen usage:

  • "I think we should go to the meet-" [speaker is interrupted]
  • "Twenty-five people attended"
  • "Well-known author"

Incorrect hyphen usage:

  • "I was thinking - and this is important - that we should..." (use dashes)
  • "The reason being - if I may say so - is quite complex" (use dashes)

#

Compound Words

Use hyphens for compound adjectives before nouns:

  • "A well-written report"
  • "A five-year-old child"
  • "A state-of-the-art facility"

#

General Rule

If the word or sentence is cut off abruptly and not continued, use a hyphen. If it's a pause in thought or parenthetical comment, use dashes or other punctuation.
