After grandma and grandpa divorce, grandpa marry another person, what do you call the grandpa's new wife? Do you call her grandma?

    The term step-grandparent is widely used, but that doesn't really answer the question of what to call your step-grandparents. Ultimately that's a personal choice.

    Call her what she asks you to call her. Commented May 5, 2021 at 16:42

According to several dictionaries, she would be your "step-grandmother".

stepgrandmother (plural stepgrandmothers)

  • The stepmother of one's father or mother and the wife of one's grandfather, usually a woman that one's grandfather marries after the divorce of one's grandparents or the death of one's grandmother.
  • The mother of one's stepmother or stepfather.

[Wiktionary]; see also

In a more personal context, it really depends on what you want to call her by.

I don't think anyone would personally call their stepmother "stepmom" either, that sounds both awkward and derogatory.

  • What does 'technically' mean here, Melon D? Does it mean 'If a suitable word for this existed, it would have to be ...'? ELU doesn't run to non-standard DIY-isms. If the word exists, please give a linked, attributed supporting reference (preferably from a dictionary). Commented May 5, 2021 at 10:01
  • @EdwinAshworth Is something like an online dictionary sufficient as reference? For instance: (wordsense.eu/stepgrandmother) Or is a more "official" source required?

  • Macmillan is very respectable, while Wiktionary is probably best here (it defines more words overall, even than OED, but has arguably less stringemt editorial policies). Commented May 5, 2021 at 10:21
  • @EdwinAshworth Thanks for letting me know. I'll edit my answer accordingly.

  • Thanks for you answer. But if someone ask "who is your grandma?", then the answer is the grandma that divorce with the grandpa or the grandpa's new wife?
