Questions & Answers about kono mise no zasshi wa shoten yori gopaasento yasui desu.

What is the function of の in この店の雑誌?

の here is the genitive (possessive) particle. It links two nouns, 店 and 雑誌, to show a relationship. In this case it means “the magazines of this store” or simply “this store’s magazines.”

Why is は used after 雑誌 instead of が?

は marks the topic of the sentence—the thing we’re talking about—namely この店の雑誌. Using が would mark 雑誌 as the subject and often emphasize it as new information. は is more neutral and sets the context for the comparison that follows.

How does より work in 書店より?

より is the comparative particle meaning “than.” You place the standard of comparison before より. So 書店より translates to “than (at) a bookstore.”

Why is the adjective 安い followed by です? Can we omit です?

安い is an i-adjective that can stand alone as a predicate:
　　この店の雑誌は書店より五パーセント安い。
Adding です makes the sentence polite:
　　この店の雑誌は書店より五パーセント安いです。
In casual speech you can drop です for brevity.

Why is 五パーセント written in kanji instead of using the symbol %?
