A simple question: what does a Greek parent say to a child or pet that there is no more food indicating that that is the end of the meal or to a pet that there are no more treats? Τελείωσε; or τελείωσαν όλα; What are the usual expressions?
In Crete and some of the islands of the Dodecanese and the Cyclades, the use of the interjection "πάπα" is far more common than "πάπαλα".
For example, similar to the use of "all gone" (#1), when a toddler or child would finish their meal, the parent would exclaim "πάπα!"- in a stretched out fashion, e.g. "πάππαααα"!
The interjection is used to denote that something is finished (as in the example above), destroyed or not working any longer, or that someone has died.
E.g. πάπα η μπαταρία, θα αγοράσουμε άλλη.
πάπα o μπακάλης, αιωνία του η μνήμη.
