Explanation
といい is used to express soft hopes or wishes about a future situation, or to suggest that a certain outcome would be good. It can convey personal hope for yourself or for someone else, and it can also be used as a gentle way of saying what would be best or preferable. The clause before といい is in plain form (dictionary form for verbs, い-adjectives in their base form, and na-adjectives or nouns with だ in their plain form). It does not state a fact; rather, it expresses a wish or suggestion about a possible outcome. Notes: - The meaning is nuanced and softer than a direct command or strong recommendation. - For na-adjectives and nouns, use the plain form + といい (e.g., 静かだといい). For verbs, use the dictionary form (e.g., 行くといい). - You can add ね or かな at the end in conversation: 静かだといいね。/ 明日雨が降らないといいかな。
雨が降らないといいね。
あめがふらないといいね。

明日が晴れるといい。
