解説 (JP): その人の性格や特徴から考えて、当然そうなるだろうと推測する時に使います。その人ならきっとこうするだろう、という予測を立てる表現です。\n\nCommon Mistakes:\n❌ からには: This makes perfect sense if you want to say, 'Since it's Yamada, he will probably get it done.' However, there is a tricky rule: you cannot connect this to Noun + 'の' (山田さんの)! The correct answer is '〜のことだから'.\n❌ だけあって: This is used to evaluate something that has already happened (e.g., 'As expected of a high-class restaurant, it's delicious'). It cannot be used for a future guess like '〜でしょう'.\n❌ せいで: 'せいで' is only used for BAD outcomes! 'Getting the job done properly' is a purely good thing, so if you use 'せいで', it sounds like you hate the fact that he's doing a good job! haha.
