Why this word is great
MECHUTAN — [Noun] A male co-father-in-law; the father of one’s child’s spouse. From Hebrew מְחֻתָּן (mechutan), a term for a relative by marriage. Unlike the sprawling, impersonal “in-law” or its precise feminine counterpart “machatayneste,” “mechutan” delineates a singular and potent male alliance. He is the man across the wedding aisle, the other signatory to a silent contract regarding grandchildren, the mirror in which your own paternal hopes are reflected—a fellowship of patriarchs linked not by blood, but by the silent, watching love for the same departing figures.
noun
- A co-father-in-law.“My father has a story of a Jewish colleague who was probably Reform. His daughter married an Israeli boy. At the wedding party which must have been in London the father asked his new Israeli mechutan if he would like to bentsch. Clearly he hadn't cleared this with him beforehand as it turned out he didn't know how to.”
