In-Word Hyphenation

Meaning also matters when you are trying to decide whether to use a hyphen within a word. For example, if you didn't press your jeans properly and you need to re-press them, you would write that with a hyphen: I need to re-press my jeans. Otherwise, people might think you mean the verb repress meaning "to stifle or put down." You re-press jeans, but repress bad memories.

  • You need to re-press your jeans.

  • You need to repress those bad memories.

A dictionary is also helpful for figuring out less obvious cases of in-word hyphenation. Fortunately, there are at least a few solid rules. You use a hyphen when when you're joining a prefix to a word that must be capitalized and when joining a letter to a word. For example, you use a hyphen in

  • Anti-American

  • Un-American

  • Pre-Mesozoic

  • X-ray

  • A-list

  • T-shirt

Also, you use hyphens to write out numbers from twenty-one to ninety-nine. For example

  • Thirty-five

  • Sixty-four

  • Ninety-three

Hyphens are a complicated topic and I promise I'll do another show about other hyphen questions in the future.
