Ptakha consists of two dots one on top, the other below the letter to add the sound of short 'A' after it. as in English letters 'can--dy' or 'ban-ker'.

zar-da Var-da        Ag-la    Kal-ba 

Ptakha can be easily recognized by the fact that the letter after it does not have a Zowei or accent therefore it needs to be pronounced together after the short A

 

Note the break down of the wrods during the pronounciation zar-da     Dar-ta    Ag-la      Kal-ba
