The colon is actually a pretty useful punctuation. It’s too bad that most people think it’s only good for making lists (and even then, most people misuse it).
The most important thing to know about colons is that the statement before the colon has to be a complete sentence, i.e., an independent clause.
In that regard, they are very much like semicolons.
However, unlike semicolons, colons do not have to be followed by complete sentences. In that sense, they are “superior” to semicolons. Perhaps that’s why semicolons have the “inferior” prefix “semi-” (half; partly).
The colon is a versatile punctuation that does a lot more than start a list of items.
Put it to good use in your next post, tweet, or … essay!
