po- (distributivní)

Distributive Prefix Po-

Level 5

The distributive prefix po- is added to imperfective verbs to show that an action affects a whole group of items, often one by one, until the entire group is exhausted.

How It Works

The distributive prefix po- is a highly productive category in modern Czech. It marks an action that is applied to multiple objects or subjects successively (postupně), until the entire group is exhausted.

1. Meaning and Nuance
This prefix emphasizes totality (every single item in the group was affected) and multiplicity. Crucially, it requires sequentiality (the action happening to each item individually or in smaller batches). For example, a simple perfective like Zavřel okna (He closed the windows) just states the result. However, Pozavíral okna explicitly encodes that he closed all the windows, going to each one sequentially.

2. Morphological and Syntactic Rules

  • Imperfective Stems: It attaches exclusively to imperfective stems, including many secondary imperfectives (verbs with suffixes like -at, -ovat, -írat). It frequently stacks on top of existing prefixes (e.g., vy-hazovat → po-vy-hazovat).
  • Plural Argument: It strictly requires a plural or collective argument. This must be a plural direct object for transitive verbs (e.g., closing windows, poschovávat věci - to hide things) or a plural subject for intransitive verbs (e.g., the hens died).
  • Reflexive Verbs: This pattern is extremely common with reflexive verbs where a plural subject undergoes the action (e.g., Všichni se poztráceli. - They all got lost).
  • Intransitive Verbs of Dying/Falling/Breaking: It is heavily used with intransitive verbs denoting dying, falling, or breaking for groups (e.g., pomřít, popadat).
  • Collocation with 'all': Distributive verbs naturally and frequently collocate with the word všichni/všechny/všechna (all) to reinforce the completion of the group.

Note: The prefix z(e)- is also an older distributive prefix. The stacked variant poz- exists because speakers stack the highly productive po- on top of older z- distributives. It attaches to verbs starting with a vowel (e.g., otvírat → zotvírat → pozotvírat, urážet → pozurážet), but it also frequently stacks before the consonant-initial prefix vy- (e.g., vytahovat → pozvytahovat, vypůjčovat → pozvypůjčovat).

3. Aspect and Tense
Adding this prefix always makes the verb perfective. It frames the entire series of individual actions as one completed macro-event. Furthermore, these verbs are strictly perfectiva tantum, meaning they cannot be made imperfective again. Forms like pozavírávat are ungrammatical and secondary imperfectives do not exist. The action is locked as a completed macro-event. Because the resulting verb is perfective, its present tense forms have future meaning (e.g., pozavírám means 'I will close them all', not 'I am closing them').

4. Contrast with Other Patterns
Do not confuse this with the Delimitative prefix po- (e.g., posedět - to sit for a while), which limits the action in time, or the attenuative prefix po- (e.g., pootevřít - to open slightly), which limits the intensity of an action and does not mean doing something to multiple items. Also, unlike Iterative verbs in -ávat and -ívat, which describe a habit over a long period, distributive verbs describe a single bounded occasion where multiple items were affected. Crucially, adding po- to determinate verbs of motion (like běžet, letět, jet) creates the future tense (e.g., poběžím, poletím, pojedu), not a distributive action. Do not translate poběžím as 'I will run one by one'.

Examples (4)

  1. Pozavíral všechna okna.

    He closed all the windows one by one.

    Word by Word: He-distributive-closed all windows.

    The prefix po- attaches to the imperfective 'zavírat' to show the windows were closed sequentially.

  2. Učitel porozdával studentům testy.

    The teacher handed out the tests to the students one after another.

    Word by Word: Teacher distributive-handed-out to-students tests.

    The action of handing out (rozdávat) is distributed across multiple students and tests.

  3. Přes zimu nám pochcípaly všechny slepice.

    Over the winter, all our hens died off one by one.

    Word by Word: Over winter to-us distributive-died all hens.

    An intransitive example where the plural subject (hens) undergoes the action sequentially.

  4. Musím ty staré věci povyhazovat.

    I have to throw those old things out one by one.

    Word by Word: I-must those old things distributive-throw-out.

    The prefix stacks on 'vyhazovat' (to throw out) to emphasize dealing with multiple items.

Common Mistakes

  • Using a singular argument with a distributive verb

    Pozavíral okno.
    Pozavíral okna.

    The distributive prefix inherently requires a plural or collective argument because the action must be distributed across multiple items.

  • Attaching the prefix to a perfective base

    Pozavřel všechna okna.
    Pozavíral všechna okna.

    The prefix must attach to an imperfective stem (like the secondary imperfective 'zavírat'), not the perfective base ('zavřít').

  • Misinterpreting the present tense form as an ongoing action

    Different MeaningTeď ta okna pozavírám.
    Teď ta okna zavírám.

    Because po- makes the verb perfective, present tense forms like 'pozavírám' actually express the future ('I will close them one by one'). To express an ongoing action, use the base imperfective verb.

Learn This First

To understand the distributive prefix po-, learners must first be familiar with the Czech aspect system (perfective vs. imperfective) and how prefixes are used to create perfective verbs. Additionally, since this prefix often describes a series of completed actions in the past, knowledge of past tense formation is required.
