Questions & Answers about Twoje mieszkanie jest na trzydziestym pierwszym piętrze.
Why do both parts of the number change to "trzydziestym pierwszym"?
In Polish compound ordinal numbers like 31st, both parts of the number act like adjectives and must match the noun's case and gender. Since the noun here is in the locative case, both trzydziesty and pierwszy take the locative neuter ending -ym.
Why is the locative case used here for the floor number?
The preposition na means "on" or "at". When you use it to describe a static location (where something is currently located), it requires the noun and any attached numbers or adjectives to be in the locative case.
What happens to the word "piętro" (floor) in this sentence?
It changes to piętrze to be in the locative case. For neuter nouns ending in -o, the ending usually changes to -e. This specific word also triggers a consonant mutation, changing the hard r into a softer rz.
Why use "Twoje" instead of "Twój" for "your"?
Mieszkanie is a neuter noun. Possessive pronouns have to match the gender of the noun they describe, so you must use the neuter form Twoje rather than the masculine Twój or feminine Twoja.
