Let’s start with the most used nicknames for Grandma.
Nana is the most common nickname for a Grandma in thirty-two states. But if someone doesn’t call their grandmother Nana, odds are they do call her Grammy or Gram, as these are relatively popular alternatives to Grandma, as well. Folks from Maine, New Hampshire, and Vermont love referring to their Grandmothers as Grammy, whereas those from New Mexico prefer the more casual alternatives of Gram and Grams.
