I got what you are trying to say but I can't explain it well, about ال it's almost like "the" in Eng, for example: look! There is a wedding, Arabic " أنظر! هنالك حفل زفاف" with article "the" in Eng we say: "Are you prepared for the wedding"? in Arabic the same we say, "هل أنت مستعد للحفل", notice that why I doubled the here (للحفل) cause the first (ل) means (for) in Eng and the second one is the article ( the) Hope it helps.
