у мене є

In Ukrainian, possession is often viewed as an object 'existing at' a person. This pattern is the neutral, everyday standard for physical possession.

1. The Components:

• У/В: The preposition meaning 'at'. Use у/в based on euphony (flow of sound).
• Possessor: The person who has the item must be in the Genitive Case.
• є: The verb 'to be' (is/are). While Ukrainian uses this to emphasize existence, it is typically omitted when describing attributes, body parts, illnesses, or when an adjective is the focus of the sentence (e.g., У неї блакитні очі — She has blue eyes).
• Object: The thing being possessed is the grammatical subject and stays in the Nominative Case.

2. Pronoun Changes:
When using pronouns with the preposition у/в, they change to the Genitive case:

• я → у мене (I have)
• ти → у тебе (you have, informal)
• ми → у нас (we have)
• ви → у вас (you have, formal/plural)

For third-person pronouns, an extra н is added to the start of the pronoun after the preposition:

• його → у нього (he has)
• її → у неї (she has)
• їх → у них (they have)

3. Nouns and Names as Possessors:
Regular nouns and names also change to the Genitive case when they are the possessor. For example:

• У брата є... (The brother has...)
• В Анни є... (Anna has...)

4. Asking Questions:
To ask a question (e.g., 'Do you have...?'), use the exact same structure with rising intonation. Ukrainian does not use auxiliary verbs like 'do' or 'does'. For example: У тебе є питання? (Do you have a question?).

5. Negation:
To say you do not have something, replace є with немає (or the shorter нема). Crucially, the object then changes from the Nominative to the Genitive case. For example: У мене немає грошей (I don't have money).

6. Past and Future:
To talk about possession in other times, є changes to match the tense:

• Past: Use був, була, було, or були depending on the object. Negative: Always use не було + Genitive (e.g., У мене не було машини).
• Future: Use буде or будуть. Negative: Always use не буде + Genitive (e.g., У мене не буде часу).

7. Alternative: The verb 'мати':
While the у мене є pattern is the default for concrete physical possession, Ukrainian also frequently uses the verb мати (to have). Unlike у мене є, мати requires the Accusative Case for the object (e.g., Я маю машину). Crucially, мати is mandatory for fixed idioms (like мати рацію — to be right, or мати на увазі — to mean/keep in mind) and is heavily preferred for abstract concepts or in formal and written registers. Additionally, мати + infinitive expresses obligation ('to have to'), e.g., Я маю працювати.
