If the word dorm is a clipped and dormitory original give some examples of word?

"Dorm" (from "dormitory") is a great example of a clipped word, also known as an abbreviation. Here are some more examples:

* Lab: from "laboratory"

* Gym: from "gymnasium"

* Photo: from "photograph"

* Phone: from "telephone"

* Flu: from "influenza"

* Exam: from "examination"

* Prop: from "property" (in theater)

* Ad: from "advertisement"

* Fax: from "facsimile"

* Bus: from "omnibus"

* Prof: from "professor"

These are all words formed by shortening a longer word, keeping the core meaning intact. Note that some clipped words (like "phone") are so common that the original word might be unfamiliar to many people.
