来るか? これ食うか? 一緒に行くか? Hi, 皆さん、こんにちは。 Welcome back to my channel and if you are new here, welcome to Real Japanese Family. So today I'm gonna be introducing you guys one of the most common mistakes Japanese learners make. First, when you want to ask someone if they want to eat something, in English, you would say, "Do you want some? " or "Do you want to eat it? " Or for example, when you ask someone if they want to come to the party, you would say, "Do you want to come as well? " or "Do you want to come? " But in Japanese, we don't say 食べたい or 来たい. It's not rude, but it's just weird. So we would just use dictionary form and say 食べる, 食べる or 来る, 来る. But when you use any interrogative words like what, when, where, who, how, then you can use the word たい. So for example, where do you want to go? You would say どこに行きたい? どこに行きたい? You can use たい with どこに. Or for example, what do you want to eat? 何食べたい? 何食べたい? It's perfect to use たい when you are using a interrogative word in a sentence, but if you are simply asking, for example, do you want to watch? Do you want to drink? Do you want to do? It's not 見たい、飲みたい、したい。 It's 見る、飲む、する。 You just use dictionary form. And important thing is that when you are asking someone higher than you, like would you like to do this? You would never use たい because it's rude. For example, if you are asking to your professor or your teacher, would you like some tea? You would not say お茶を飲みたいですか。 It's rude to say that, so you would say お茶はいかがですか。 お茶はいかがですか。 Or we would simply say 先生、お茶どうぞ and hand it to the teacher. Or for example, if you are saying, "Would you like to come with us? " or "Would you like to do it with us? " You would say 先生もご一緒にいかがですか。 先生もご一緒にいかがですか。 So my point is you don't use たい when you are meant to be polite. And another common mistake is that when we ask a question formally, we have to put か at the end, right? Like what is this? これはなんですか。 これはなんですか。 Or did you go somewhere on the weekend? You could say 週末どこかに行きましたか。 週末どこかに行きましたか。 So when you ask a question formally, you have to put this か as a question marker. But when we speak casually, we use plain form, right? Plain form is basically what you use when you speak with friends. So plain form of, for example, 食べます is 食べる, I eat, 食べない, I don't eat, 食べた, I ate, 食べなかった, I didn't eat. And when we use plain form, we don't use か as a question marker. So we don't say 週末どこかに行ったか。 週末どこかに行ったか。 We just say 週末どこかに行った。 週末どこかに行った。 Or for example, are you coming as well, Miku? You would not say ミクも来るか。 ミクも来るか。 You would say ミクも来る? ミクも来る? Maybe Luffy from One Piece would say 来るか or これ食うか or 一緒に行くか because he is very confident and a bit arrogant character. You know, my dad or men above 50s would say this to me, like 来るか or 行くか. I mention this mistake because you sound very weird and also a bit, like, arrogant or looking down on the listener. So please be careful not to put か at the end when asking a question casually. You can make a sentence a question by raising your intonation up, but not by adding か at the end. So are you coming with me? You say ミクも来る? ミクも来る? It goes up at the end.
