Difference between ほど and かぎり

They're so different that I've never thought those two words same. I think you're fooled by the English definition because "to the extent" can certainly cover both use cases to some extent. ...

Other uses of the たら conditional

What does the verb after なくちゃ or なくては mean?

You are thinking of なくちゃ as must, but it's really just a contraction of なくては. なくてはならない and なくてはいけない are used to mean "must", and sometimes the final verb is dropped and なくちゃ by itself is used as a ...
