How do you say 'grandma' in Cantonese Chinese?

奶奶 ma ma - Grandmother on dad's side.

(Unlike the sound for mother, the tone for this one goes down progressively.)

婆婆 po po - Grandmother on mother's side.

(It sounds like "Pau" from the name "Paul". Just don't include the "L".)

祖母 jo mo - Grandmother (general)

(Just in case you don't know if it's mom's or dad's.)
