Behemoth

I have been reading The Economist, and there is a formulation which surprises me.
It is not about the term -''behemoth''-, I know that it means something monstrous or gigantic,but more about the shape of the sentence :

"But the new-comer has powerful backers, including China's biggest bank and shipping company as well as Russian energy and commodity behemoth.

Personally, I would say ''and behemoth commodities''.
Is behemoth an adjective one can put at the end of the sentence?

Thanks in advance 👁 Wink ;)

Behemoth is not an adjective, but a noun, at least in this case. "Behemoth", as you said, means something gigantic, but it is not the commodity that is gigantic. The word here refers to a gigantic energy and commodity company.

The sentence does seem a little incomplete, however. It seems that there should be the name of a company (e.g. "Energia" or something like that) at the end, OR that behemoth should be in plural ("...as well as Russian energy and commodity behemothS").

Behemoth is a noun. Its original meaning is "a large beast." It is a transcription of the Hebrew word for "beast" into Latin, or English, letters. (Actually, it's a mis-transcription; it's a transcription of the Hebrew plural, meaning "beasts," but is used as singular in English.)

Here, the behemoth is not a beast, but is a large, powerful organization.

Commodity is used here as an adjective, to describe the business of this organization. It is large and powerful in the energy and commodity business.

By the way, was "a" left out before "Russian?" It would read more naturally that way.

Thanks for your answers, I occurred to me that behemoth was a noun, but it dissatisfied me, probably because of the hazy construction of the sentence (or my far from perfect knowledge of English ^^ ).
I took care to transpose the exact sentence, so I did not omitted any ''a'' or name of company, albeit I deleted in brackects words.

Perhaps the bracketed words changed the structure enough to make the changes that sendintheclowns and I suggested unnecessary.

The actual sentence:

But the newcomer has powerful backers, including China’s biggest bank (ICBC) and shipping company (Cosco) as well as a Russian energy and commodity behemoth (EN+ group).

An important "a" was indeed left out.
