so it be還是so be it

So be it是對的，我查了一下翻譯辭典，有這個字。

意思-->(表示完全接受)就那樣好了

例句： If he doesn't want to be involved, then so be it.

翻譯：要是他不想參與，那就隨他的便好了。

So be it 的英文解釋：

used to show that you accept sth and will not try to change it or

cannot change it

Let it be so, I accept it as it is. For example, If you can't change the reservation, so be it; I'll travel on Monday. This phrase, often given as a translation of the Hebrew (and Greek and Latin) amen, has been employed in the current sense since about 1600.

阿門（Amen So be it）：在基督教中，「阿門」是在禱告完畢在胸錢化十字架所吟唱的詞句；其由來是希伯來語，有「正是如此」、「希望的確能如我所願」 意，在英文中則是「So be it」
