Affectionate, familiar term for one's own grandmother or an elderly woman addressed as a grandmother figure. Used within the family or with close acquaintances.
I love the rice balls my grandma makes for me.
Can refer to any elderly woman in a familiar, sometimes slightly informal way. Not necessarily a relative; often used by children or in casual speech.
I always go to my grandma's house to visit on weekends.
The old lady in my neighborhood always greets me on the street.
During summer vacation I went to my grandma's house in the countryside.
When I was little, I was always spoiled by my grandma.
おばあちゃん means grandma/an old woman, while おじいちゃん is the matching term for grandpa/an old man.
おばあちゃん is the intimate, childish term used within the family, while おばあさん is the more polite, standard word used to address or refer to elderly women respectfully.
おばあちゃん is a warm, familiar family term, whereas 祖母 is the neutral, formal word used when referring to one's own grandmother in writing or polite conversation with outsiders.
おばあちゃん (with a long ā sound) means grandma or an elderly woman, while おばさん (short a) means aunt or a middle-aged woman, so the vowel length changes the meaning entirely.
