Instrumental of route
The bare instrumental case is used to describe the route or space you travel through, answering the question "which way?" (kudy?).
How It Works
In Czech, the bare instrumental case (without any preposition) is used to express the route, path, or space through which movement occurs. It answers the question kudy? (which way? / through where?). This pattern is frequently triggered by verbs of motion (such as jít, jet, procházet), verbs of leading or directing (e.g., vést - to lead), as well as verbs of perception (e.g., dívat se oknem - to look through a window).
Paths, Surfaces, and Spaces:
The instrumental of route is used for moving through 3D spaces (lesem - through a forest, oknem - through a window) as well as along surfaces or paths (ulicí - along the street, cestou - along the path). Note that for surfaces, the bare instrumental (ulicí) can sound more literary or formal. In everyday spoken Czech, people often prefer the preposition po + locative (jít po ulici). The word cestou is frequently used as a lexicalized adverb meaning 'on the way' or 'along the way'.
Route vs. Destination:
It is crucial to distinguish between the route (kudy?) and the destination (kam?). For example, Jdu lesem means 'I am walking through the forest' (the forest is the route), whereas Jdu do lesa means 'I am walking into the forest' (the forest is the destination).
Related Concepts:
While physical routes use the instrumental of route, abstract communication channels (like poslat poštou - to send by mail, or platit převodem - to pay by transfer) are grammatically classified as the instrumental of means (answering čím? - with what?), though the conceptual analogy of a 'channel' is very similar.
Key Differences from English 'Through' and 'Via':
English relies heavily on prepositions, but Czech offers nuances:
- Bare Instrumental (lesem, ulicí): The standard way to express the route of travel through an environment. For cities, using the bare instrumental (Prahou) implies driving around within the city itself.
- skrz + accusative (skrz zeď): Specifically used for physically piercing or penetrating a substance or obstacle (like a drill through a wall). Avoid overusing it for normal environments like forests, where the bare instrumental is preferred.
- přes + accusative (přes ulici, přes Prahu): Used for crossing a surface or barrier from one side to the other, or for traveling via a waypoint (e.g., jet přes Prahu - to travel via Prague).
Examples (5)
- Šli jsme lesem až k řece.
We walked through the forest all the way to the river.
Word by Word: Walked we forest-INSTR all-the-way to river.
The forest (lesem) is the space or volume through which the movement happens.
- Zloděj utekl oknem.
The thief escaped through the window.
Word by Word: Thief escaped window-INSTR.
Openings like windows and doors naturally take the bare instrumental to show the route of exit or entry.
- Dívám se oknem na zahradu.
I am looking through the window at the garden.
Word by Word: Look myself window-INSTR onto garden.
The instrumental of route is also triggered by verbs of perception, not just verbs of motion.
- Tato silnice vede dlouhým tunelem.
This road leads through a long tunnel.
Word by Word: This road leads long-INSTR tunnel-INSTR.
Verbs of leading or directing, such as 'vést' (to lead), are core triggers for the instrumental of route.
- Procházeli jsme úzkou chodbou.
We were walking through a narrow corridor.
Word by Word: Walked-through we narrow-INSTR corridor-INSTR.
Adjectives modifying the route must also be in the instrumental case (úzkou chodbou).
Common Mistakes
Using 'přes' (across) when describing movement along a route.
Different MeaningŠli jsme přes ulici až na náměstí.Šli jsme ulicí až na náměstí.'Šli jsme přes ulici až na náměstí' is correct, but 'přes' means crossing from one side to the other. To express walking along a street as a route, use the bare instrumental case (ulicí).
Adding the preposition 's' (with) before the route.
Different MeaningZloděj utekl s oknem.Zloděj utekl oknem.'Zloděj utekl s oknem' is correct, but 's' means 'together with', so it says the thief ran off carrying the window. To express a route, use the bare instrumental case without any preposition: 'utekl oknem'.
How It Connects
Learn This First
To understand the instrumental of route, a learner needs to have learned the morphological forms of the instrumental case. Additionally, since this pattern describes the path of movement, familiarity with basic verbs of motion and the general system of spatial orientation in Czech is required.
- s / se + InstrumentalInstrumental After S and Se
The learner must first be familiar with the basic endings and forms of the instrumental case before using it for more abstract functions like expressing a route.

Understanding spatial adverbs and the concept of direction versus location is necessary to distinguish the instrumental of route from other spatial cases.

Related Patterns
- Instrumental of means
Both patterns use the bare instrumental case without a preposition. While the instrumental of route answers 'kudy?' (which way?), the instrumental of means answers 'čím?' (with what?), which is used for abstract channels like sending something by mail (poštou).
Level 2 - o / po / při + LocativeLocative After O, Po, And Při
The preposition 'po' with the locative case (e.g., po ulici) is the standard everyday spoken choice for movement along a surface, whereas the bare instrumental (ulicí) is more literary or formal.
Level 2 - do + Genitive (Direction)Into or to with Direction
Contrasts the destination of a movement (kam? - do lesa) with the route taken to get there (kudy? - lesem).
