Questions & Answers about Mój plan jest ważny.

What does Mój mean, and why is it in this particular form?

Mój translates to my. In Polish, possessive adjectives must agree with the noun they modify in gender, number, and case. Since plan is a masculine noun in the nominative singular case, mój appears in its masculine singular form. If the noun were feminine (e.g., książka – book), you would use moja instead.

What role does jest play in the sentence?

Jest is the third person singular form of the verb być (to be). It acts as the copula, linking the subject Mój plan to the predicate adjective ważny. Together, they form the complete statement Mój plan jest ważny (My plan is important).

How does the adjective ważny agree with the noun plan, and what changes would occur with a different noun?

Ważny is a predicate adjective, and it is used here in the masculine singular nominative form to match plan. Polish adjectives must agree with the noun in gender, number, and case. If the noun were feminine, for instance, the adjective would change to ważna (as in moja decyzja jest ważna – My decision is important). Similarly, for a neuter noun, it might become ważne.

Why is there no article (such as the) before plan in this sentence?

Polish does not use articles like the or a/an. Definiteness and indefiniteness are usually inferred from context and other elements, such as possessive adjectives. In Mój plan, the word mój already helps specify the noun, eliminating the need for a separate article.

Is the word order in Mój plan jest ważny fixed, or can it be rearranged for different nuances?

The sentence follows a common Subject (Mój plan) – Copula (jest) – Predicate (ważny) structure, which is standard in Polish declarative statements. However, Polish word order is relatively flexible due to its inflectional nature. Changing the order—for example, Ważny jest mój plan—can shift emphasis but may also alter the stylistic tone or focus within the sentence.
