Some traditional nicknames for a grandmother are Grandma, Granny, Grams, Gramma, and Nana. There are also trendy nicknames, like Ama, Granan, Mammi, Mammoo, Noma and Onie. Some playful grandmother nicknames are: GoMa, Grimmi, Jamma, Mommo and Nooni.
The choice of a nickname usually depends primarily on whether the grandmother prefers one that is common or one that is unusual and unique. A grandmother may decide that she wants a name completely different from the one she associates with her own grandmother, choosing a more trendy, modern option. Alternatively, she may decide to use a traditional family nickname as a way of keeping her own grandmother's memory alive.
There are nicknames for grandmothers that evolve from a child's inability to pronounce a name, such as Ammo or Bamaw (for grandma) or Budna (for grandmother). Some grandmothers' nicknames come from family circumstances, such as Bella, or Beautiful in Italian, for a grandmother possibly feeling that a more traditional nickname makes her feel old. Some international names for a grandmother include Bomma (Flemish), Savta (Hebrew) and Avo (Portuguese).
