What's the difference between hyphen and perhaps?

Hyphen


Definition:

  • (n.) A mark or short dash, thus [-], placed at the end of a line which terminates with a syllable of a word, the remainder of which is carried to the next line; or between the parts of many a compound word; as in fine-leaved, clear-headed. It is also sometimes used to separate the syllables of words.
  • (v. t.) To connect with, or separate by, a hyphen, as two words or the parts of a word.

Perhaps


Definition:

  • (adv.) By chance; peradventure; perchance; it may be.

Example Sentences:
