「たらいい・といい」の情報

When any of the conjunction particles that carry the meaning of 'if' (たら, , or ) are paired with the い-Adjective, いい, they will express the desired result of the speaker. These all translate to 'it would be nice if (A)'. However, the speaker's level of certainty about the result being 'good' will change slightly, depending on the particle.
ばいい - Hypothetically, (A) happening would be good. (Lowest strength/certainty)
たらいい - When (A) happens, it will be good. (Medium strength/certainty)
といい - The result of (A) is good. (Strongest/most certain)
To use , たら, or といい, first add the conjunction particle to the end of any verb, and then attach the い-Adjective, いい.

    OK, yeah, this is one of those patterns that can tend toward ~といい due to the way と expresses natural consequence, in a way that だら doesn’t. The たらいい・といい grammar point doesn’t discuss this, but the といい one does. Thing is, that entry even says といい tends more strongly toward, “I hope,” or, “I wish.” They’ve translated it, “It would be nice if … wouldn’t it?” here. It does seem like something is slightly out of sync. I think a better translation would probably be, “I hope the weather tomorrow and the day after will be clear.” That’s based on the information provided in the といい grammar point.

    If you encounter this sentence again, I would definitely report it, and point back to this discussion here. Sometimes things slip through the cracks like this. Or maybe one of the staff can point out why this sentence is an exception.
