What are typical Scottish names for grandmas?

The proper Scottish Gaelic word for Grandmother is "seanmhair," but this word is very formal and is commonly supplanted by "Nana" or "Nanna" in modern Scottish families. Other Gaelic dialects common in Ireland and Scotland commonly use "Mamó" as an informal name for Grandmother as well.

Traditional Gaelic languages are spoken far less frequently in Scotland, Ireland and Wales than they were in the past, so Scottish families are just as likely to say "Gran" or "Granny" as their English neighbors are. "Nan" is a very common nickname for an older woman and does not have to refer to a grandmother.
