Here's how it works:
* Two words: For example, "long" and "sleeved"
* Hyphen: Combine the words with a hyphen: "long-sleeved"
* Descriptive adjective: The hyphenated word "long-sleeved" now describes something as having long sleeves.
Here are some more examples:
* High-pitched (high + pitched)
* Well-known (well + known)
* Part-time (part + time)
* Red-hot (red + hot)
Hyphening is a common way to create new adjectives and make your writing more concise and descriptive.
