How to use

The noun 'drzwi' (door) is a plurale tantum (it exists only in the plural). It requires plural verbs and adjectives (e.g., 'otwarte drzwi' — open door/doors). The genitive plural form is 'drzwi' (e.g., 'brak drzwi'), and the instrumental is 'drzwiami'. When counting doors, use collective numerals (e.g., 'jedne drzwi', 'dwoje drzwi').
