Macmillan has only the entry **[Home Town][1]**.
<br>
Oxford also has only the entry **[Home Town][2]**, but all the examples suggested have **hometown** written.
<br>
Cambridge has only the entry **[Hometown][3]**.

1) Which is the word I should use: **Home Town** or **Hometown**?

I've read [here][4] that:

***Home town** is used for “My **home town** is Flower Mound.” Home is modifying the noun, town.
<br>
**Hometown** is an adjective, as in “My **hometown** memories.”*

2) Is this all right? Do both words exist, one as a noun and the other as adjective? If it is the case, why the dictionaries don't have both entries?
