10.19 · Kinship Terms · Kinship Relations Involving Successive Generations
grandmother the mother of one’s own mother or father (with a possible connotation of affection) In a number of languages it is necessary to distinguish between the grandmother on one’s father’s side and the grandmother on one’s mother’s side. There is no positive indication in 2TI 1:5 as to the particular relationship involved, but one may assume that the grandmother Lois was the mother of Eunice, and therefore it would be the grandmother on the mother’s side.
