What is the sign of hiphen in punctuation?

The hyphen (-) is a punctuation mark that has several uses. However, it's important to distinguish it from the en dash (–) and the em dash (—), which are longer and used in different contexts.

Here are some common uses of the hyphen:

* Joining words to form compound words: Examples: *long-term*, *well-being*, *self-made*.

* Indicating a range of numbers or dates: *1990-1995*, *pages 10-20*.

* Creating compound adjectives: *state-of-the-art*, *easy-to-use*, *two-sided*.

* Creating compound nouns: *mother-in-law*, *brother-in-law*, *passer-by*.

* Splitting words at the end of a line: This is usually done when a word is too long to fit on the line.

Note: The hyphen is not the same as the dash. The en dash is longer than a hyphen and is used to indicate a range of numbers or dates, and to separate related words. The em dash is even longer and is used to indicate a break in thought or a pause in the sentence.
