يوجد لفظ " لقيط" و هو الطفل أو الرضيع الذى وُجِد ملقى لا يعرف أحد أبواه.
and by the way it IS different from "Orphan"
لقيط = Foundling :
an infant that has been abandoned by its parents and is discovered and cared for by others.
while Orphan = يتيم
an orphan's parents are known ,they're just both or at least one of them is dead.
I hope the difference is clear.
