I have a question about ''Hebrew''
"Aba" אבא = dad
"Av" אב = father
But אב is rarely used in speech
It is more of an official/archaic language. For instance, in the news they will mostly use "אביו של הילד" (the child's father) and not "אבא של הילד". The same goes about biblical Hebrew.
It's kind of like English. Father is more formal than Dad.
is more formal than
However, av is more formal than father is in English, so both dad and father can be translated as aba.
Daddy is אבאל'ה abale.
Yes they're the same
Av means father in Hebrew. For instance, there is a prayer called "Avot v'Imahot" (Our Fathers and Mothers) blessing the patriarchs and matriarchs.
