could somebody please tell me what the following mean, i think they are greek sayings..

1) babatns
2)mamatns

thankyou

If you mean 1) babathes 2) mamathes, then it is 1) daddies, 2) mommies.

The words, as you write them, are the words for 'grandma' and 'mama'.
The form as you write it implies possession by the speaker. The phrase is incomplete. Example.
Η Βαβά της Ελένης - Helen's Grandmother. the 'της' is equivalent to the possesive 's (Helen's).
The same for the second phrase. Μαμά της Ελένης =
Helen's mother.
I hope I'm clear enough.
