půl / jeden a půl

Half and One and a Half

Level 4

Půl means "half" and jeden a půl means "one and a half." In basic sentences, they force the counted noun into the genitive singular.

How It Works

The behavior of půl (half) and jeden a půl (one and a half) depends on their role in the sentence:

1. In Nominative and Accusative cases (Subjects and Direct Objects)
Both expressions act as quantifiers and force the counted noun into the genitive singular. Remember that jeden must still agree with the noun's gender:

  • Masculine: jeden a půl roku (one and a half years)
  • Feminine: jedna a půl hodiny (one and a half hours)
  • Neuter: jedno a půl kila (one and a half kilos)

2. In Oblique cases (Instrumental, Locative, Dative, Genitive)
In oblique cases, the counted noun takes the target case in the singular. While the word půl itself is indeclinable (e.g., před půl rokem), the phrase jeden a půl fully declines, meaning jeden must also match the target case.

  • Instrumental: s jedním a půl milionem (with one and a half million)
  • Dative: k jednomu a půl roku (to one and a half years)

3. The Conversational Workaround
Because declining jeden a půl in oblique cases can feel clunky, native speakers frequently invert the phrase in everyday speech. Instead of před jedním a půl rokem, you will usually hear před rokem a půl (a year and a half ago).

4. Telling Time
When expressing time, půl is followed by an ordinal number in the feminine genitive singular, looking forward to the next hour. For example, půl třetí means 2:30 (literally "half of the third hour"). Note an important exception for 12:30: Czechs use the cardinal number jedna in the genitive (půl jedné), not the ordinal první. Additionally, in everyday spoken Czech, the formal ending -é often changes to -ý (e.g., půl druhý, půl osmý), except for soft adjectives like třetí.

5. Verb Agreement and Literary Forms
When jeden a půl acts as the subject of a sentence, it behaves like a numeral quantifier. This means the verb must take the neuter singular form in the past tense (e.g., Jeden a půl roku uběhlo.). You might also occasionally encounter the older, literary one-word equivalent půldruhého (one and a half).

Examples (6)

  1. Cesta trvá jedna a půl hodiny.

    The journey takes one and a half hours.

    Word by Word: Journey takes one and half of-hour.

    Nominative/Accusative context: 'jedna' agrees with the feminine noun 'hodina', which is forced into the genitive singular.

  2. Koupil jsem půl kila jablek.

    I bought half a kilo of apples.

    Word by Word: Bought am half of-kilo of-apples.

    'Půl' forces the neuter noun 'kilo' into the genitive singular ('kila').

  3. Šel do důchodu s jedním a půl milionem.

    He went into retirement with one and a half million.

    Word by Word: Went into retirement with one and half million.

    Instrumental context: 'jeden' and 'milion' both decline into the instrumental singular.

  4. Přestěhovali se před rokem a půl.

    They moved a year and a half ago.

    Word by Word: Moved themselves before year and half.

    The common conversational workaround: inverting the phrase to avoid the clunky oblique declension 'před jedním a půl rokem'.

  5. Sejdeme se v půl třetí.

    We will meet at half past two.

    Word by Word: Will-meet ourselves at half of-third.

    Time telling: 'půl' is followed by the ordinal number looking toward the next hour.

  6. Jeden a půl roku uběhlo velmi rychle.

    One and a half years passed very quickly.

    Word by Word: One and half of-year passed very quickly.

    When 'jeden a půl' is the subject, the past tense verb takes the neuter singular form ('uběhlo').

Common Mistakes

  • Using the plural form of the noun instead of the genitive singular.

    Bydlím tady jeden a půl roky.
    Bydlím tady jeden a půl roku.

    Because English uses the plural ('one and a half years'), learners mistakenly use the Czech plural. Fractions involving 'půl' strictly govern the genitive singular of the counted noun.

  • Forgetting to decline 'jeden' to match the gender of the counted noun.

    Film trvá jeden a půl hodiny.
    Film trvá jedna a půl hodiny.

    The word 'jeden' must agree in gender with the counted noun (feminine 'jedna' for 'hodina'), even though the noun itself is forced into the genitive case.

  • Translating 'half past' literally using a cardinal number.

    Vlak přijede v půl tři.
    Vlak přijede v půl čtvrté.

    When telling time, 'půl' is followed by an ordinal number looking forward to the next hour. 'Half past three' (3:30) is 'půl čtvrté' (half of the fourth hour).

Learn This First

To learn 'půl' and 'jeden a půl', learners must understand how the numeral 'jeden' changes for gender (jeden/jedna/jedno) and how quantifiers in Czech trigger the genitive case for the noun that follows (e.g., půl hodiny).
