This is the 10570th most frequent Turkish word.
büyükannesi
"Her grandmother."
Here, 'büyükannesi' refers to 'his grandmother,' showing familial possession and context in Turkish.
Ali'nin büyükannesi ona güzel bir atkı ördü.
Ali's grandmother knitted a beautiful scarf for him.
In this case, 'büyükannesi' is used indeterminately, leaving the possessor to be inferred from context.
Büyükannesi çok yaşlı ama hala iyi yürüyebiliyor.
His/her grandmother is very old but can still walk well.
This instance demonstrates specifying possession through explicit naming of the possessor, Ayşe.
