Definition
Meaning
One's grandmother (informal, affectionate term).
Can refer to a type of leavened, oven-baked flatbread (naan) in South Asian cuisine. In computing slang, a 'NaN' (Not a Number) is a numeric data type value representing an undefined or unrepresentable value.
Linguistics
Semantic Notes
The familial term is used primarily as a proper noun or vocative. The culinary term is a mass noun but can be pluralized ('nans') informally. The computing term is a highly technical acronym.
Dialectal Variation
British vs American Usage
Differences
'Nan' for grandmother is far more common and established in British English. In American English, 'Nana' or 'Grammy' are more typical; 'nan' is understood but less frequent. The culinary term 'naan' is spelled and used identically in both varieties.
Connotations
In British English, 'nan' is warm, working-class, and familial. In American English, if used, it can sound quaint or British. The computing term is strictly technical.
Frequency
High frequency in UK informal/family contexts. Low frequency in US for the familial sense. Medium frequency for the culinary term in both.
