IS there a way to say it in Hebrew? “
THAT is THE HEBREW. Mechutanim is Hebrew for the parents of the chosson or kallah. It comes from the shoresh OF CHOSSON, Ches,Suf, Nun. We see it in the Torah by Yisro Chosein (father-in-law of) Moshe. Mother-in-law is probably choh-sen-ess. The mechutan (grammatically formed in Binyan Pu-al, which is the passive form of Binyan Pea-el and pronounced with a sefardic tuf,not suf) is the parent of one of the parties to the chasunah. Plural is mechutanim. The Yiddish pronunciation for that Hebrew word is “machetonim.” Kind of like saying Mishpoocha, for the original Hebrew “Mishpacha.”
