Punctuation marks can get you out of a lot of trouble. If used correctly they create effect and keep the reader’s interest, if used incorrectly or too much they slow your work down and bore.
1) Hyphen -
Hyphen is used to connect words that act as a single idea, usually before a noun. Don’t use with adverbs (-ly). Do not hyphenate fractions introduced with indefinite articles a or an.
- Before a noun
State-of-the-art design, 25-year-old midfielder, pin-point crossing, goal-scoring charts, etc.
- To signify a single idea
Wide-eyed, no-brainer, re-elect, ex-player, world-class, pre-assister, etc.
Hyphenate spans of distance or time:
1998-2002, 40-50 yards, etc.
2) Em dash —
This is the king of punctuation marks and your right-hand man when trouble hits. Use its power wisely. It can take over the places of the parentheses, comma and colon.
- When you need to provide explanation for something, squeeze it with em dashes on both sides.

4) Semicolon ;
- Use it to split sentence that are related and work together.

An interesting case here if you want to use the em dash:
Some people write with a word processor; other—with a pen or pencil.
The sentence is a bit slow but grammatically correct.
5) Comma ,
- To separate elements in a series, insert and in the last one.
