How to say, "try to __", "have to __"


For some reason I can't remember how to say "try to **_" or "have to (must)
_** " in Japanese. How can I say this? Any variations you can include would be
appreciated.




Try to ~

> ~ようとする (Does not give any information whether the action was actually
> carried out in entirety)
>
> ~てみる (Try for the sake of seeing the result, does **not** have negative
> implication as in "to try (unsuccessfully )" )

* * *

have to(must) ~

> ~なければならない
>
> ~なくては｛ならない・いけない｝
>
> ~ないといけない
>
> ~ねばならない

~なくては is often contracted to ~なくちゃ

~なければならない can also be contracted and have ならない elided to form "~なけりゃ" or
"~なきゃ" which is used informally.
