The Haggadah says:
וַאֲפִילוּ כֻּלָּנוּ חֲכָמִים, כֻּלָּנוּ נְבוֹנִים, כֻּלָנוּ זְקֵנִים, כֻּלָנוּ יוֹדְעִים אֶת הַתּוֹרָה
Listing 4 different qualities means that each one is not sufficient, and those are not overlapping, but it sound weird, for example, זקן we know that stands for זה קנה חכמה, and includes two others.
What are those 4 distinctive qualities and why being חכם or זקן is just not enough?
