“Mommle”
Or as my nephew and others including my mom mis-spell it, “Mah-Mal”. But “mommle” best describes in English phonetics how they say it.
It’s all thanks to my older nephew who attempted to call to his grandma at an early age, not knowing what to call her, I guess. I suppose he heard his mom and me call her “Mom”.
It’s stuck. His sisters adopted it and so even have Mom’s elder “step-grandchildren”! LOL 35year-olds seriously calling her “Mommle”. She likes it because she’s vain and it’s hard for people to tell it means “grandma” and thus, “old woman”.
