That's theoretically perfect, yes. But it sounds just a bit unusual. But we can work with it.
Let's see. You stand up from the table and I ask you where you are going. You can say any of the following:
Sörért. - For beer
Hozok sört - I bring beer
Hozok még sört - I bring (some more) beer
Akarok hozni sört - I want to bring beer
Sört akarok hozni - I want to bring beer
Akarok hozni még sört - I want to bring (some more) beer
Megyek sörért - I go for beer
Kérek sört - I (am going to) ask for beer
and many more...
After a few rounds, "Akarok sört" will fit in perfectly.
Also, when you stand up, you can ask the others:
Ki kér sört? - Who wants beer?
Ki kér még sört? - Who else wants beer? / Who wants some more beer?
Ki akar sört? - Who wants beer?
Akar valaki sört? - Does anyone want beer?
Kér valaki sört? - Does anyone want beer?
and many more...
So, the bottom line is, it is perfectly fine to "akar", as long as it does not stand for "please give me". Then it would be rude. It is almost like "I demand".
Oh, and, if you want to include a number (three beers), you can insert it in any of the above sentences, immediately before "sör".
Heheh. I have heard that most Hungarians actually don't see their suffixes as noun cases, but that might be too easy an excuse for the poor Indo-European mind. Memorising all the nominal suffixes (or ragok, as they're called in Hungarian) is pretty simple, but you have to develop a feeling for what roles the words takes in the sentences, which especially English is seriously lacking.
Oh, you're right. The feeling is the key. It is somewhat the same for us learning Indo-European languages ;) (These suffixes are tricky, there are slight differences in dialects [but the dialects are not that bad as in other languages] and even the less educated Hungarians make terrible things to them :D )
No, no. The suffix -t determines the accusative case which identifies the direct object, in this example here it's what you ask for. "I (nominative) ask for a beer (accusative)." Whether it's one beer or more isn't important in this sentence.
If you want to specifically ask for more than one beer, you use the accusative of the plural, which'll be "kérek söröket".
I don't speak hungarian and know nothing at all of it, but judging from slavic cases wich I do know, that shouldn't work. Direct object (accusative) would be one beer or I want a beer which is this that is written here. Now what would some beer (genitive case version in hungarian) be i have no idea.
You got the connection of direct object and accusative right, but Hungarian has very little to do with the Slavic languages. They have their own little corner and have been pretty resistant to adopting most Slavic influences.
Hungarian doesn't have a genitive case (they have possessive suffixes which they lavishly use, though), but for forming the plural of words, they simply add -k. Most often with appropriate vowels. Sörök, for instance, for multiple portions of beer. And now the fun part: They use this plural form except if there's a number determiner. So, any number, or words like 'few', 'some', 'many', and so on. "I would like some beers" would be "Néhány sört kérek."
Kérni is the infinitive form - to ask for.
Kérek is the conjugated form for 1st person singular present indefinite. Or simply "I ask for [something]."
In dictionaries you will find this verb listed as kér, which is the 3rd-person singular form, "He/she asks for [something]". The other conjugational forms are made by just adding various suffixes to this base form.
