Questions & Answers about Учора я був вдома.
What part of speech is учора and what does it mean?
учора is an adverb meaning yesterday. It tells you when something happened.
Why is the verb був used here, and what is its infinitive?
був is the masculine singular past tense form of the verb бути (to be). It agrees in gender and number with the subject. If the speaker is female, you’d use була instead of був.
What case or form is вдома, and how does it translate?
вдома is an adverb meaning at home. It comes from в + дома, but in modern Ukrainian it’s a frozen adverbial expression rather than a declined noun phrase.
Why isn’t there a preposition before вдома?
Because вдома already carries the meaning “in/at home.” To express movement toward home, you would use додому (to home). Adding another preposition before вдома would be redundant.
Can you omit the pronoun я in this sentence?
Yes. Ukrainian often drops subject pronouns when the verb form makes the subject clear. Учора був вдома is perfectly acceptable if context indicates who you are.
Where is the stress in учора?
The stress falls on the second syllable: учора́ (u-cho-RA).
Is the word order fixed, or can you rearrange the elements?
Ukrainian has relatively flexible word order. The neutral order is Учора я був вдома, but you can also say Я вчора був вдома (emphasizing the subject) or Я був вдома вчора (emphasizing the time) without changing the basic meaning.
