po- (delimitativní)
Delimitative Prefix Po-
The prefix po- turns imperfective activities (like spát or sedět) into perfective verbs that mean doing something for a short, relaxed period (pospat si, posedět).
How It Works
1. Formation and Aspect
While po- can attach to perfective verbs to create meanings like "slightly", the "one by one" meaning (distributive po-) derives from imperfective bases. For the delimitative meaning, it attaches directly to imperfective atelic verbs (activities and states). The resulting verb is strictly perfective (a perfectivum tantum). Because it is perfective, its present tense form expresses the future: popovídáme si (we will chat for a while). Never use the auxiliary budu with these verbs!
2. The "For a While" Rule and Telicity
Delimitative po- verbs are the mainstream linguistic counterexample to the rule that perfective verbs must have a result or change of state (telicity). Posedět is perfective, but it is completely atelic—there is no result, just a temporal boundary. Therefore, unlike most perfective verbs that require "in [time]" (za + accusative), delimitative verbs take "for [time]" using the accusative of duration: Pospal si hodinu. (He slept for an hour.)
3. What Not to Confuse It With
- Motion verbs and sports: The po- in půjdu or pojedu creates an imperfective future, not a delimitative perfective (note that pů- is historically a lengthened variant of po-). To say "I will run around for a bit" (like a child or a dog), use the perfective verb derived from the indeterminate base: poběhám si. However, for active sports and hobbies done for exercise or pleasure (like jogging, swimming, or playing a game), Czech uses the prefix za- instead of po- (e.g., zaběhat si, zaplavat si, zahrát si).
- The prefix pro-: While po- means a short, casual time, pro- means spending a long or entire period doing something (e.g., prosedět celý den - to sit the whole day away).
Examples (5)
- Chvíli jsme poseděli a pak jsme šli domů.
We sat for a while and then went home.
Word by Word: A-while we-are sat-for-a-while and then we-are went home.
A classic delimitative verb. The action of sitting is bounded by a short, indefinite time.
- Potřebovali si o tom v klidu popovídat.
They needed to chat about it in peace for a while.
Word by Word: They-needed themselves about it in peace to-chat-for-a-while.
The combination of po- and the reflexive 'si' adds a cozy, conversational tone to the action.
- Odpoledne si hodinku pospal.
He slept for an hour in the afternoon.
Word by Word: Afternoon himself hour slept-for-a-while.
Notice the accusative of duration ('hodinku'). Even though the verb is perfective, it takes 'for an hour', not 'in an hour'.
- Včera večer jsem si hezky početl.
I had a nice read for a while last night.
Word by Word: Yesterday evening I-am myself nicely read-for-a-while.
The prefix po- combined with 'číst' (to read) and the reflexive 'si' expresses reading for a while for one's own pleasure.
- Až přijedete, dáme si kávu a popovídáme si.
When you arrive, we'll have coffee and chat for a while.
Word by Word: When you-arrive, we-will-give ourselves coffee and we-will-chat-for-a-while ourselves.
Because 'popovídat si' is perfective, its present tense form ('popovídáme si') automatically expresses the future.
Common Mistakes
Using the preposition 'za' (in) for the time duration because the verb is perfective.
Pospal si za hodinu.Pospal si hodinu.Delimitative verbs are perfective but atelic (they have no end goal or result). Therefore, they require the accusative of duration ('for an hour'), not the preposition za ('in an hour').
Using the imperfective future auxiliary 'budu' with delimitative verbs.
Budu si popovídat s kamarádkou.Popovídám si s kamarádkou.Because po- makes the verb perfective, its present tense form automatically expresses the future. You cannot use budu with perfective verbs.
How It Connects
Learn This First
To understand the delimitative prefix po-, learners must first grasp the Czech system of verbal aspect (perfective vs. imperfective). Since this prefix creates perfective verbs that denote a limited duration, learners should also be familiar with how to express time duration in the accusative and how to form the past tense, as these verbs are most commonly used to describe completed activities that lasted for a short period.
- Basic aspect pairs
Understanding the basic concept of verbal aspect (perfective vs. imperfective) is essential before learning how specific prefixes like po- modify aspectual meaning.
Level 2 - Accusative of duration
Delimitative verbs are often accompanied by time expressions in the accusative (e.g., 'chvíli') to specify the duration of the activity.

Related Patterns
- siBenefactive Si
Delimitative po- verbs frequently combine with the benefactive si to express doing an action for one's own pleasure, relaxation, or comfort.
Level 2 - Perfective present with future meaning
Because delimitative verbs are strictly perfective, their present tense forms are used to express future actions without the auxiliary 'budu'.
Level 3 - půjdu / pojeduSuppletive Future of Motion Verbs
Learners often confuse the delimitative po- with the po- used to form the imperfective future of determinate motion verbs. They function completely differently.
