-nak/-nek

The dative case is one of the most versatile tools in Hungarian. Its functions include:

• Indirect Object & Beneficiary: Marking the recipient ('to') or the beneficiary ('for') of an action (e.g., 'I give a book to Peter' or 'I buy a gift for Mom'). Note: If 'for' means 'in exchange for' or 'for the purpose of', Hungarian uses the causal-final case (-ért) instead.
• Possession: Hungarian uses the nekem van construction (To me there is...) to show ownership.
• Possessive Attribute: In a possessive phrase, the dative case can mark the possessor. This is mandatory when using demonstratives (e.g., ennek a fiúnak a könyve - 'this boy's book') or when the possessor and possessed are separated.
• Naming: Used with the verb hívni (to call/name) to state what someone is called (e.g., Péternek hívnak - 'They call me Peter' / 'I am called Peter').
• Role or Purpose: Expressing what role something serves or what it is intended as (e.g., ajándéknak - 'as a gift').
• Adjectives: Used with common adjectives to express how something affects someone (e.g., fontos nekem - 'important to me').
• Modal Verbs: The logical subject of verbs like kell (must), szabad (may), and lehet (possible) takes the dative case. When using a personal infinitive (e.g., mennem kell), the dative pronoun (nekem) is optional and mostly used for emphasis. With a bare infinitive (e.g., menni kell), the dative is mandatory if you want to specify the person (nekem kell menni).
• Experiencer Verbs: Expressing physical or emotional states where the person is the 'experiencer', such as fáj (to hurt - e.g., Fáj nekem), hiányzik (to miss - e.g., Hiányzol nekem), ízlik (to taste good - e.g., Ízlik nekem), and tetszik (to like - e.g., Tetszik nekem, which literally means 'is pleasing to me').
• Specific Verbs: Many other common verbs require the dative. For verbs of communication like mond (to tell), the recipient takes the dative while the thing being said takes the accusative. Other verbs often take a direct object in English or express an outcome, but need the dative in Hungarian, such as sikerül (to succeed - e.g., Sikerül nekem), válaszol (to answer), telefonál (to call on the phone), köszön (to greet/thank), hisz (to believe), megbocsát (to forgive), and segít (to help - note that unlike English, in Hungarian you help to someone).
• Postpositions and Adverbs: The dative case is strictly required before certain common postposition-like words, most notably köszönhetően (thanks to — e.g., neked köszönhetően) and megfelelően (according to — e.g., ennek megfelelően).

Question Words:

• kinek? (to/for whom?)
• minek? (to/for what? / why?)
