The mother of one of your parents is your grandmother. The sister of one of your parents is your aunt. And, you guessed it, the brother of one your parents is your uncle.
Considering this, what is your mother's aunt to you?
Your mother's aunt is your great-aunt or grandaunt (all one word).
Accordingly, what are your parents uncle to you?
Your father's uncle is your great uncle or granduncle. Your granduncle's child is your father's cousin.
Your father's father is called your grand-father, yet your father's uncle is typically called your great-uncle (or so it seems with anybody I converse with).
