Here's a breakdown:
For a male speaker:
* Grandmother (mother's side): Γιαγιά (Ya-ya)
* Grandfather (mother's side): Παππούς (Pap-poos)
* Grandmother (father's side): Μαμά (Ma-ma)
* Grandfather (father's side): Μπαμπάς (Bam-pas)
For a female speaker:
* Grandmother (mother's side): Γιαγιά (Ya-ya)
* Grandfather (mother's side): Παππούς (Pap-poos)
* Grandmother (father's side): Μαμά (Ma-ma)
* Grandfather (father's side): Μπαμπάς (Bam-pas)
Note: The terms for "grandmother" and "grandfather" on the father's side are the same as the words for "mother" and "father," respectively.
This is common in some languages, reflecting the strong family bond and the importance of the paternal side.
