Verb / Adjective / Noun + し

The conjunction し is used to list multiple reasons, causes, or states in an emphatic way. It often implies that there are other factors in addition to the ones mentioned. When used at the end of a sentence, it can suggest a reason without stating the conclusion explicitly.

Verb / い-Adjective informal form + し

For Verbs and い-Adjectives, し follows the informal form (present or past).

The food is delicious, and what's more, it is cheap.

It was raining, and besides, I was tired.

Noun / な-Adjective + だ/だった + し

For Nouns and な-Adjectives in the present tense, だ is required before し. For the past tense, だった is used.

The town is quiet, and what's more, it is beautiful.

He was a teacher, and besides, he was a parent.

Note

When using し with Nouns or な-Adjectives in the present tense, だ must be added before し. In polite speech, the ます or です forms can also be used before し, though the informal form is more common in casual conversation.
