“First, a man is not complete until he is married. Then, he’s FINISHED!”
That’s why the bride is called a Kalla, from the Lashon of VaYichulu – when Hashem finished the earth.
That is also why the groom wears a burial shroud called a kittel – from the same lashon of Bar Ketalla – sentenced to death.
Marriage is more that a word; it is a sentence.
