Questions & Answers about Mój dom i twój dom są równie duże.
Why is the noun dom repeated in the sentence rather than being mentioned only once?
In Polish, when a compound subject is formed by two possessive phrases—mój dom and twój dom—the noun is repeated to clearly show that each possessive adjective refers to its own distinct object. This repetition avoids ambiguity about whether the speakers are talking about one shared house or two separate houses.
Why is the adjective duże in its plural form even though each dom is singular?
Even though each individual dom is singular, the sentence refers to two houses as a compound subject. Therefore, the adjective must be in the plural form (duże) to agree with the plural subject formed by the two separate houses.
What is the function of the adverb równie in this sentence?
Can the noun dom be omitted in the second part, writing something like Mój dom i twój są równie duże?
While native speakers might sometimes omit the noun in informal conversation, repeating dom in each phrase is preferred for clarity—especially in written or formal contexts—since it emphasizes that both possessive adjectives refer to separate houses.
