「といい」の情報

One of the regular uses of the と particle is to express 'if'. However, unlike some other structures (like なら, たら, and ば), と implies that the 'if' result of と is something that will definitely happen, or is a natural consequence of (A) happening. When combined with the い-Adjective いい, it means 'if (A), it would be good'.

This construction may be used with any phrase ending in a word in its standard form.

  • 明日(あした)は学校(がっこう)に行(い)きたくないな～、雪(ゆき)が降(ふ)るといいな。

    I don't want to go to school tomorrow. It would be great if it snows.

    • 今夜(こんや)のパーティーは楽(たの)しいといいね！

      I hope your party tonight is fun! (Hoping for someone else's sake)

      • 先輩(せんぱい)が言(い)っていることが本当(ほんとう)だといいね！

        If what senpai is saying is true, it would be good!

        • 「今夜(こんや)の夕食(ゆうしょく)は魚(さかな)だといいな～」と弟(おとうと)が言(い)っていました。

          My little brother was saying 'I hope dinner tonight is fish'.

          Because と expresses a 'certain' outcome, the 'good' in this grammar construction often sounds quite strong, leading to といい regularly being translated closer to 'I hope (A)', or 'I wish (A)'.

          There are several situations in which this grammar point can be used to express that you are hoping something for yourself, or hoping something for someone else. This is primarily determined by the use of な, or んだけど (hoping for yourself), or ね (hoping for others/mutual benefit).

          • 明日(あした)は晴(は)れるといいな。

            I hope it clears up tomorrow. (Hoping for your own benefit)

            • 明日(あした)の試合(しあい)で勝(か)つといいんだけど相手(あいて)が強(つよ)いから自信(じしん)がない。

              I hope to win the tournament tomorrow, but since my opponent is formidable, I am not confident. (Hoping for your own benefit)

              • 来週(らいしゅう)は彼氏(かれし)が来(く)るといいね。

                I hope your boyfriend comes next week. (Hoping for another's benefit)

                Caution

                When this expression finishes with けど, けれども, or が, it can imply that there are some external factors that will make the desired result difficult to achieve.

                • 明日(あした)の朝(あさ)に荷物(にもつ)が届(とど)くといいんだけど。（今夜(こんや)から雪(ゆき)が降(ふ)るから配達(はいたつ)が大変(たいへん)そう）

                  I hope my package arrives tomorrow morning. (However, it is going to start snowing tonight, so delivery seems like an issue)

                  • 宝(たから)くじに当(あ)たるといいんだが。（一枚(いちまい)しか買(か)っていないから当(あ)たらないと思(おも)う）

                    I hope I win the lottery. (But since I only bought one ticket, I don't think I will)

                      I hope
                      I wish
                      you should

                      Structure

                      • Wishing for others/inside group :
                        Desired Outcome + といい + です + ね
                        Desired Outcome + といい + ね
                      • Wishing for oneself :
                        Desired Outcome + といい + なぁ
                        Desired Outcome + といい + ん/の + です + が
                        Desired Outcome + といい + ん/の + だ + けど

                      If といい means “to hope” the verb has to be non-controllable , or controllable but in potential form .

                      Controllable verb:
                      帰るといい - You should go back home
                      帰れるといいね - I hope you can come home.

                      Non-controllable verb:
                      雨が降らないといいね - I hope it won’t rain.
                      [Cannot be used to give advice]

                      @xBl4ck Nice spot! We recently got the Japanese for this sentence updated and forgot to fix the translation. Cheers!

                    • deltacat3

                      deltacat3

                      楽しいといいんですが。
                      I hope it is fun.

                      Whats が doing at the end of this sentence?

                    • matt_in_mito

                      matt_in_mito

                      The が at the end of the sentence implies that the speaker gets the feeling that it might not be fun.

                    • deltacat3

                      deltacat3

                      Ahhhh! I see how that’s working. The implied omission insinuates the speakers reluctance, hesitance, etc… Thank you! @matt_in_mito

                    • matt_in_mito

                      matt_in_mito

                      Japanese is a very high-context language and you have to read between the lines all the time. This is a prime example of that.

                      I don’t know if this has been reported before, but isn’t this point (といい) a duplicate of the grammar point https://bunpro.jp/grammar_points/212 (covers both といい and たらいい) ?

                      If not, what’s the difference?

                    • Howl_UK

                      Howl_UK

                      There is a Japanese Ammo video for this grammar point. I’m adding these links to each grammar discussion as I find them so let me know if this is annoying!

                      What is なぁ? Is that a small あ on purpose?

                    • matt_in_mito

                      matt_in_mito

                      You will often see a small ぁ at the end of a sentence like どうしようかなぁ - it gives the impression that the speaker is trailing off into thought.

                    • natiiix

                      natiiix

                      I believe these small vowels at the end of a sentence are similar to using ～ or ー at the end of a sentence instead of a full stop. The sentence ends with a prolonged pronunciation of the last word, indicating an ongoing thought process or empathy of the writer/speaker.

                      It’s kind of like phonetic spelling in English, where you intentionally mangle words to convey certain additional emotion in your writing.

                    • MikkaT

                      MikkaT

                      Hi, what does this part mean? it is not clickable and it is the only example which uses a な in both parts of the sentence.
