Főleg fokhagymát használunk.

It is built into the verb használunk.

Hungarian often leaves out subject pronouns when they are clear from the verb ending. Here:

• használunk = we use

So you do not need mi for we unless you want emphasis or contrast:

• Mi főleg fokhagymát használunk. = We mainly use garlic.

Főleg is an adverb meaning mainly, mostly, or especially depending on context.

In this sentence, it tells you that garlic is the primary thing being used. It does not mean only.

Compare:

• főleg = mainly, mostly
• csak = only

So this sentence does not say garlic is the only thing used, just that it is the main one.

Because fokhagyma is the direct object of the verb, and Hungarian marks direct objects with the accusative ending, usually -t.

So:

• fokhagyma = garlic
• fokhagymát = garlic, as the thing being used

There is also a small stem change:

• final short -a often becomes long -á before a suffix

So:

• fokhagyma + -t → fokhagymát

This is very common:

• alma → almát
• szoba → szobát

Because the noun is being used in a general, non-specific way.

Here, garlic means garlic as an ingredient or substance in general, not a particular garlic that both speakers know about. Hungarian often leaves out the article in this kind of statement.

So this feels like:

• using garlic in general

If you were talking about a specific, known garlic, you would be more likely to use an article:

• a fokhagymát

But in a general sentence about what you use, no article is very natural.

This is a very important Hungarian grammar point: Hungarian has two kinds of verb conjugation:

• indefinite
• definite

Here, használunk is the indefinite form.

That is used because the object is not definite/specific. Fokhagymát here means garlic in general, not the garlic.

If the object were definite, you would usually use the definite form:

• A fokhagymát használjuk. = We use the garlic. / It is the garlic that we use.

So:

• használunk = we use it / we use something non-specific
• használjuk = we use it, with a definite object

The ending -unk shows:

• present tense
• first person plural
• indefinite conjugation

So használunk means we use.

The basic verb is:

• használ = use

Then Hungarian adds an ending to show who is doing the action.

Also, the form is -unk rather than -ünk because of vowel harmony. The verb stem használ- contains back vowels, so it takes a back-vowel ending.

Yes, it is singular, and that is normal.

Just like English often uses singular mass nouns for ingredients and substances, Hungarian does the same. Here fokhagyma means garlic in a general sense, not individual garlic items.

So singular is the natural choice.

A plural such as fokhagymák would usually suggest separate kinds, units, or specially counted items, which is not the normal meaning here.

Yes, Hungarian word order is flexible, but different orders can change the emphasis.

The given sentence is natural and straightforward:

• Főleg fokhagymát használunk.

Hungarian often puts the most important or focused part right before the verb. Here, főleg fokhagymát works together to highlight what is mainly used.

Other versions are possible, but they may sound different in emphasis:

• Mi főleg fokhagymát használunk. → emphasis on we
• Fokhagymát használunk főleg. → more marked; can sound like an afterthought or a different emphasis

So the original order is a very natural one.

A few key pronunciation points:

• Hungarian stress is normally on the first syllable of each word.
• ő is a long front rounded vowel, similar to German ö, but longer.
• gy is a soft consonant, roughly like dy in some pronunciations of duke
• sz sounds like English s
• s by itself sounds like English sh
• á is a long vowel, roughly like the vowel in father

So watch especially these parts:

• FŐ-leg
• FOK-ha-gy-mát
• HASZ-ná-lunk

If you already know IPA, a rough pronunciation is:

• [føːlɛg fokhɒɟmaːt hɒsnaːluŋk]

Sometimes, but they are not all the same.

• főleg = mainly, mostly
• leginkább = mostly, most of all, to the greatest extent
• inkább = rather, preferably, instead

So:

• Leginkább fokhagymát használunk. is quite close to the original.
• Inkább fokhagymát használunk. changes the meaning. It suggests we use garlic rather / instead, often in contrast to something else.

So főleg is the best choice for a plain statement about what is mainly used.

Yes. It is a perfectly normal Hungarian sentence.

It sounds like something you might say when talking about:

• cooking
• food habits
• ingredients
• what your family or restaurant tends to use

Because Hungarian often omits subject pronouns and articles when they are not needed, the sentence is short but fully natural.
