must, have to, can be, may be

Postby fragulistic » Thu 02.16.2006 6:44 pm

I was watching NHK today and they had an english lesson for Japanese viewers but I watched it anyways to see if I could learn something. They were talking about sentences with "must", "have to", "can be" , "maybe".

I think I get the gist of must and have to, but I was wondering if someone could help me with can be and may be. Ok here is what I got.

僕の店長が承るので、僕は稼げるちがない。

I might not have undertsood the program I was watching, but is 〜ちがない must?
Secondly where would it appear in a sentence, after the verb it explains?

If must is doing something that's demanded of you, have to is doing something you don't necessarily have to do right away.

I have an example sentence to put up but I don't have the time. If someone could help explain these things better and also can be and may be it would be much appreciated.

Lot's of grammar like that comprises of saying "I can't not do this".

Probably the most common is 〜なければならない

全部食べなければならない

I have to eat it all.

This is usable in pretty much situation you can imagine saying "have to", "must", etc.

Another one is 〜てはいけない

You can use the 〜ては form for lots of stuff, like 入ってはできない (you can't enter), 読んではだめ (you can't read it [If you read it it's だめ!]), then you can use the negative form, and slap on いけない (can't go?) to mean if they don't do it, they can't continue (basically the same meaning as above).

この宿題をしなくてはいけない

There's a lot more but... I too don't have time ;)

Oh, by the way, does なければならない really mean "If you don't do it you won't become"?

The easy answer is "no" -- but if you want a really long grammatical and etymological explanation, it can be provided. ;)

You know I do!

I love finding out WHY things are the way they are. I really think it helps one to fully understand everything.... (that is, if they're past the point where they just get confused).

Please, explain away.
