Predicate Adjective in the Instrumental
In Ukrainian, when an adjective describes a subject after a linking verb (like був 'was' or став 'became'), it usually shifts from the nominative to the instrumental case. This signals that the quality is a state in time rather than a permanent essence.
How It Works
The predicate adjective in the instrumental case is the standard grammatical requirement in modern Ukrainian when an adjective follows an explicit linking verb in the past, future, or infinitive. While it often emphasizes a temporary state or a role, it is primarily a structural rule for these specific verbs.
1. Core Trigger Verbs:
The instrumental case is required after:
- бути (past: був, була, було, були)
- бути (future: буде, будуть)
- бути (infinitive: я хочу бути корисним)
- стати (to become)
- залишатися (to remain)
- працювати (to work as)
- вважатися (to be considered)
- називатися (to be called)
- виглядати (to look/appear)
- здаватися (to seem)
2. Standard vs. Present Tense:
In the present tense, Ukrainian uses a zero copula and the adjective stays in the nominative: Він щасливий (He is happy). However, as soon as the verb is expressed (e.g., Він був щасливим), the instrumental becomes the standard choice in modern speech.
Examples (5)
- Сергій хвилювався, але намагався здаватися спокійним.
Serhiy was worried, but he tried to seem calm.
Word by Word: Serhiy worried, but tried to seem calm.
The verb 'здаватися' (to seem) requires the adjective to be in the instrumental case 'спокійним'.
- Я хочу бути щасливим поруч із тобою.
I want to be happy next to you.
Word by Word: I want to be happy next with you.
The infinitive form 'бути' (to be) triggers the instrumental case for the following adjective 'щасливим'.
- Вона працювала відповідальною за проєкт.
She worked as the person responsible for the project.
Word by Word: She worked responsible for project.
The verb 'працювати' (to work as) triggers the instrumental case for the adjective 'відповідальною'.
- Цей будинок вважається історичним.
This house is considered historical.
Word by Word: This house is considered historical.
The verb 'вважатися' (to be considered) requires the instrumental case 'історичним'.
- Після дощу вулиця виглядала чистою.
After the rain, the street looked clean.
Word by Word: After rain street looked clean.
The verb 'виглядати' (to look/appear) triggers the instrumental case 'чистою'.
Common Mistakes
Using the nominative case after the verb 'to become' (стати).
Він став успішний.Він став успішним.In Ukrainian, the verb 'стати' obligatorily governs the instrumental case. Using the nominative here is a common error for English speakers.
Using the instrumental case in the simple present tense.
Він є щасливим.Він щасливий.While 'є щасливим' is grammatically possible in very formal logic, it sounds unnatural in daily speech. Use the nominative with the zero copula for the present tense.
How It Connects
Learn This First
To use a predicate adjective in the instrumental, a learner needs to understand adjective case agreement (specifically the instrumental endings for all genders and plural), the governing behavior of copular verbs like 'бути' and 'стати', and how these verbs function in the past tense where this construction is most common.
- Adjective Case Agreement
Learners must know how to decline adjectives into oblique cases, specifically the instrumental case endings, to form a predicate adjective.
Level 2 - стати / бути + InstrumentalInstrumental Predicate After Стати and Бути
This pattern establishes the fundamental rule that the verbs 'бути' (to be) and 'стати' (to become) govern the instrumental case for nominal predicates.

This is the noun-equivalent of this pattern, where nouns also take the instrumental case to show roles or professions.
Level 2 - Predicate Adjective in the Nominative
This is the contrasting pattern used in the present tense or to show permanent characteristics.
Level 4 - був/була/було/булиPast Tense of Бути
The past tense of 'to be' is the most common trigger for the instrumental predicate adjective.
Level 2 - будеFuture Copula and Existence with Буде
The future copula also triggers the instrumental case for adjectives.
