Copy edited by Harlon Moss || By Janet White || Updated on September 28, 2023
"Gammy" is an informal or affectionate term for a grandmother, while "Grandmother" is the formal term for a female grandparent.

Key Differences

"Gammy" and "Grandmother" both refer to a female grandparent, but their usage and connotations differ. "Gammy" is a colloquial, endearing term, often used by younger children when addressing or referring to their grandmother.
"Grandmother," on the other hand, is a more formal and standard term. It clearly defines the relationship between an individual and their parent's mother without any added layers of emotion or informality.
The word "Gammy" can be likened to other diminutive or affectionate names for grandparents, such as "Nana" or "Granny." These terms often originate from a child's early attempts at speech or are passed down through family traditions.
"Grandmother" is universally understood and is used in official contexts, documents, and when clarity is paramount. It is a term that transcends cultural and linguistic boundaries and is recognized globally.
While "Gammy" might be more prevalent in certain cultures or families, "Grandmother" serves as a universally accepted term to describe one's maternal or paternal mother.
