clarify and clear

用樓上的例子說明和更正：
clear is an adjective and verb,
The sentence is very clear(adjective). 這句子很是清楚。
Your voice is loud and clear(adjective). 你的聲音(意見)很是清晰和明朗。
Please clear (verb) all the obstacles. 請清除所有的障礙物。

clarify is a verb,
I would like to clarify that I didn't steal anything from your shop.
我要澄清一下，我沒有偷走你商店內的任何東西。

voice 的例子是(意見)為正確意譯，聲音為文字的直譯。

clear is an adjective, e.g. The sentence is very clear.
clarify is a verb, e.g. I would like to clarify that I didn't steal anything from your shop.
