Translation:We are going to hurry; the wedding begins in ten minutes.
We are going to hurry the marriage begins in 10 minutes ... why was this not accepted?
A wedding is not a marriage. Marriage refers to the relationship following the wedding ceremony, the long term sharing of two lives. Wedding refers to the specific ceremony that unites two people in marriage. One could conceive of a wedding without a marriage, unfortunately. For instance if the couple were wedded but immediately one had a heart attack and died.
