Vowels That Come and Go
Some vowels come and go. Many masculine nouns lose the e or o in their last syllable when they take an ending: pes → psa (dog), otec → otca (father), deň → dňa (day).
How It Works
A vowel that drops out. In many masculine nouns, the e or o in the last syllable appears only in the nominative singular (and in the accusative for things). As soon as an ending is added, it disappears:
- pes → psa, psovi (dog)
- otec → otca, otcovia (father)
- deň → dňa, dni (day)
- Peter → Petra
- zámok → zámku (castle)
- kúsok → kúska (piece)
Some nouns also change another vowel at the same time: vietor → vetra (wind), stôl → stola (table).
Learn the genitive with the noun. Not every e or o drops out. Compare otec, otca with domček, domčeka (little house) and človek, človeka (person). A dictionary gives the genitive so you can see which kind of noun it is.
A vowel that appears. Feminine and neuter nouns often have no ending in the genitive plural. When the stem would end in two consonants, a vowel is added between them, usually ie, e, o or á:
- okno → okien (windows)
- sestra → sestier (sisters)
- matka → matiek (mothers)
- hra → hier (games)
- vojna → vojen (wars)
- jedlo → jedál (dishes)
After a long syllable the added vowel is short: rozprávka → rozprávok (fairy tales), not rozpráviek.
Where you meet these forms. The genitive plural follows numbers from five up and words of amount: päť okien, veľa hier. See genitive plural endings and five and more.
This is different from the extra vowel in prepositions such as vo and so; see prepositions with an extra vowel.

Common Mistakes
Keeping the vowel that should drop out.
Nemám pesa.Nemám psa.The e in pes appears only in the nominative. Every other form is built on ps-.
Keeping the vowel in otec.
To je dom môjho oteca.To je dom môjho otca.Otec drops its e when it takes an ending: otca, otcovi.
Adding a masculine ending instead of a vowel.
Náš byt má päť oknov.Náš byt má päť okien.Neuter nouns in -o have no ending in the genitive plural, and okno gains ie: okien.
