Miscellaneous is also sometimes used as a noun to refer to a group or collection of things that are not related to each other. For example, a "miscellaneous assortment of items" might include anything from paper clips to toys to clothing.
The word miscellaneous comes from the Latin word "miscellus", which means "mixed". It is often used in a derogatory way to describe something that is disorganized or cluttered. However, it can also be used in a positive way to describe something that is interesting or unusual because of its variety.
