Questions & Answers about Нога важлива для ходьби.
Why is the copular verb є (to be) omitted in Нога важлива для ходьби, and why is the adjective важлива in the nominative case rather than the instrumental?
In Ukrainian, the present‐tense copula є is normally dropped in simple statements. When you leave out є, the predicate adjective stays in the nominative case to agree directly with the subject. If you do include the verb, the adjective typically shifts to instrumental:
Нога є важливою для ходьби.
Why is the adjective важлива (important) ending with -а, not -ий as in важливий?
Adjectives in Ukrainian must match the noun’s gender, number and case. Нога is a feminine singular noun (it ends in -а), so the adjective takes the feminine nominative ending -а, giving важлива. The masculine form важливий would not agree with нога.
Why doesn’t Ukrainian use an article before нога, like the leg or a leg?
Ukrainian has no definite or indefinite articles. Context alone tells you whether you mean “a leg” or “the leg.” If you need to be specific you can add a demonstrative like ця нога (this leg).
Why is the noun ходьба in the genitive case as ходьби after the preposition для (for)?
