Stacking Reasons
し lists reasons that point the same way. Unlike から, which gives one reason, し implies there are several — and often that you have not bothered listing them all.
- この店は安いし、おいしいし、よく来ます。(This place is cheap, and tasty, so I come often.)
Formation
Attach to the plain form, keeping だ on nouns and な-adjectives:
| Type | + し |
|---|---|
| Verb | 行くし |
| い-adjective | 安いし |
| な-adjective | 静かだし |
| Noun | 休みだし |
It also works with polite forms: 安いですし.
One し Implies More
Even a single し hints at unstated reasons:
- 今日は疲れたし、帰ります。(I'm tired — among other things — so I'm going home.)
That "among other things" is the whole point. から would state your one reason flatly; し leaves room.
Trailing Off
Ending on し, with nothing after it, is a soft way to decline or hint:
- ちょっと高いし…(It's a bit expensive, and…)
The listener fills in the rest. Same politeness move as trailing けど.
Not Just for Reasons
し can simply list qualities with no conclusion attached:
- 彼は頭もいいし、スポーツもできる。(He's clever, and good at sport too.)
Pair it with も on each item for a natural rhythm.
し vs から vs て
| Pattern | Feel |
|---|---|
| から | one specific reason |
| し | several reasons, not exhaustive |
| て form | plain sequence or cause, no listing |
