Grètil
Any one of the other grandparents of your grandchild. The parents of your son- or daughter-in-law. In a sense, a grètil is the inverse of a cousin: your cousin is a member of another family who shares your grandparent; whereas a grètil is a member of another family who shares your grandchild.
Etymology: As the word cousin is a French contraction of a phrase meaning “mother’s sister’s child”, grètil is a contraction of the French phrase “grand-mère de la petite-fille”, meaning “grandmother of the granddaughter”. (And it forms equally well from the corresponding grandfather and grandson phrases.)
Bonus: if you don’t care for your grètils, you can refer to them as “regrètils”.

We had our grètils over for Christmas dinner; the four of us are almost never together, and the grandkids were delighted.
