How to say 'my gran' or address your own grandmother casually
The most common affectionate term for one's own grandmother. Used by both children and adults within the family. Can be used to address her directly or refer to her in conversation.
Gran, can I eat this?
I went to my gran's place yesterday.
A more casual, slightly rough but affectionate term. Common in some families or among older children. Can sound a bit blunt if not used with warmth.
Gran, how are you?
The neutral, formal term for 'grandmother'. Used when speaking about your own grandmother in formal contexts or to non-family members. Not used to address her directly.
My grandmother lives in Kyoto.
How to talk about another person's grandmother respectfully
Very polite and respectful term for someone else's grandmother. Often used in formal situations or when speaking to someone of higher status.
How is your grandmother?
Polite and standard way to refer to someone else's grandmother. Can also be used by children to address their own grandmother politely, though おばあちゃん is more common.
How to politely address or refer to an elderly woman who is not your grandmother
Can be used to address an elderly woman in a friendly, respectful way, similar to 'ma'am' or 'granny' in English. Use with caution; some may find it presumptuous. Safer when the person is clearly of grandmotherly age.
Avoid using with women who might not appreciate being called 'grandma'. In doubt, use おばさま or simply すみません.
Are you all right, ma'am?
Sometimes used by children or in very casual, friendly contexts to address an elderly woman, but can be overly familiar. Not recommended for adult learners unless you have a close relationship.
Granny, you dropped this.
Use おばあちゃん for your own gran in casual family talk. Use 祖母 when speaking formally about your own grandmother to outsiders. Use おばあさん for someone else's grandmother or to politely address an elderly woman.
祖母 is a humble term used only for your own family. Using it for someone else's grandmother is rude. Use おばあさま or おばあさん instead.
I met Tanaka-san's grandmother.
