See the introduction to Hungarian possession for a broad description.

The biggest difference between this an owning single objects is the letter i.

First, decide how many objects are owned.

If one item is possessed, go to the single objects page.

If several items are possessed you need to check that the number of objects is qualified but not quantified. That is, if we have "some" but you don't know the exact number.

If you know the exact number, go to the single objectspage.

Then, select the owner of the object.

The owner is either I, you, he/she/it, we, you (pl), or they.

Finally, apply the relevant endings.

Owner	Charactistic ending	Endings	Examples
én	-im	-im/aim/eim	almáim	dobozaim	kezeim	házaim
te	-id	-id/aid/eid	almáid	dobozaid	kezeid	házaid
ő	-ai	-ai/ei	almái	dobozai	kezei	házai
mi	-ink	-ink/aink/eink	almáink	dobozaink	kezeink	házaink
ti	-itok	-aitok/eitek	almáitok	dobozaitok	kezeitek	házaitok
ő(k)*	-ik	-aik/eik	almáik	dobozaik	kezeik	házaik

alma = apple
doboz = box
kéz = hand, becomes kez- when endings applied
ház = house

Note how alma + aim -->  almaaim --> almáim
See the note on lengthening trailing vowels

^*  See the explanation here: single possession

There are certain nouns that take an additional -j- before the regular endings. These words, despite ending in a consonant, do not take the vowel-initial ending directly but instead take this -j- version.

They usually take this special version in the third person only (i.e. his, their).

In a way these nouns are irregular and you must simply learn them. Often a dictionary or glossary will indicate to you this fact.

The best example is probably barát friend. You can see all of its versions below.

• barátaim my friends
• barátaid your friends
• barátjai his friends
• barátaink our friends
• barátaitok your friends
• barátjaik their friends
