Need understand with .......

Assalamun alaikum

I learning Arabic and learnt about jumlah ismiyyah - nominal sentence.

I read here http://muslimmatters.org/2008/01/07/...-of-the-quran/

that Alhamduilah is jumlah ismiyyah
What i wanted to ask is:-

Alhamdu illah

Is Alhamdu- mubtadah
for Allah - illah - khabar

Isnt Allah a noun so how can alhamdu be a noun isnt alhamd it a adjective


What about Allahu Akbar is the jumlah ismiyyah.. Allahu being mubtadah adn akbar being khabar......

interesting stuff all these..:-)

I hope some1 can help me understand this
