| JLPT N4. Used in both conversation and writing, although it is a casual expression. |
し is used to list clauses. It can be used with verbs, adjectives, and nouns, but with na-adjectives and nouns the auxiliary verb is required.
The difference between ～し and ～たり is that ～し is used to list related things. For example, if someone asked you why you liked Wada-sensei you might reply:
| Wada-sensei is clever, amusing and, moreover, he’s kind. |
All the above are related—they are reasons why you like Wada-sensei. One typical sentence structure is to list two reasons and then give the result at the end.
| 【Reason】し【Reason】し【Result】 |
| あのお |
| That restaurant is cheap and the food is good—I like it. |
| There’s not much overtime, you can easily take holiday—that company is popular among new graduates. |
し is often used at the end of the sentence to give a belated or secondary reason for something.
| Wada | You going to the picnic tomorrow? |
| ロス | そうだよ。 |
| Ross | Yeah. Besides, I don’t have anything else to do. |
| Hana | I was thinking about getting a job during the summer holidays. What do you think? |
| Daichi | It’s better than hanging around the house all day? You can also save some money. |
