Summary is a noun, and "summery" is an adjective, but they sound alike and both describe something short. A summer feels like a short piece of a long year, and a summary is a short statement about a longer piece. When a long speech or writing needs retelling in a short amount of time, a summary conveys the meaning in fewer words. Often a book cover has a summary of what's inside, and an introduction has a summary of the main points in a chapter. http://www.chetantourandtravels.com/
