Hyphens

Hyphens are used for two seperate different words

Hyphens need to be used the right way in order to understand it better.

Such as:

Eye-opener, Air-condition, Well-known, One-half, or One-third

Not used right:

Antiaircraft

And the difference between a minus and hyphen

Some words don't need hyphen's

Because the prefixes and suffixes help the word out.
