Deverbal Nouns

A huge slice of the Czech vocabulary is built out of verbs. From one verb stem, Czech can spin off a noun for the action (the reading), the doer (the reader), the result (the earnings), and the tool (the vacuum cleaner) — each marked by its own suffix that tells you instantly which role the noun plays. English does something similar with -ing, -er, and -tion, but Czech's suffixes are more systematic: the suffix is the role-label, so once you read the suffix you know what kind of noun it is. This page covers the deverbal patterns beyond the all-purpose verbal noun in -ní/-tí (treated in its own page) — the agent, result, and instrument nouns.

The pure action nouns in -ní/-tí (čtení "reading", psaní "writing", mytí "washing") are the most regular deverbal type and are covered in depth in verbal nouns and nominalization. Here we look at the suffixes that build a noun naming the agent, the result, or the instrument of the verb.

Agent nouns: the doer

Agent nouns name the person (or sometimes the thing) that performs the verb. The two most productive suffixes are -tel and -č, both forming masculine animate nouns that decline accordingly.

-tel: the most productive agent suffix

The suffix -tel attaches to the verb stem to name a doer, usually a person in a role or profession. It is the closest Czech equivalent to English -er/-or in teacher, writer, reader.

Because -tel nouns are masculine animate, they decline like pán/muž-type nouns: učitel, učitele, učiteli, učitele, učiteli, učiteli, učitelem in the singular, with the animate plural učitelé.

-č: doer (and tool)

The suffix -č also forms agent nouns, often for occupations tied to a concrete activity. Crucially, -č is two-faced: it builds both people who do the action and the machines that do it — a point we return to under instruments.

-ář / -ník: more agent suffixes

Two further suffixes round out the agent set. -ář (with palatalization of the stem) names doers tied to a thing or material — čtenář ("reader," from číst via the čt- stem), lhář ("liar," from lhát), kuchař ("cook," from kuchyně/kuchat). -ník names a person associated with an activity or domain — pracovník ("worker," from pracovat), zaměstnanec uses yet another suffix, -ec.

Result and action nouns

A second family names the act itself or its result/product, as opposed to the doer. These are usually inanimate, and the suffix varies.

-ek: result or process

The suffix -ek (a masculine inanimate ending) often names a result or a bounded process derived from a prefixed verb.

Notice vznik and pokles take a zero suffix (no added ending at all) — the bare prefixed stem becomes the noun. This zero-suffix nominalization is extremely common in administrative and journalistic Czech, where it compresses a verb into a noun: vznik společnosti ("the founding of the company"), pokles cen ("a fall in prices").

-ka: action or result (feminine)

The suffix -ka is multipurpose, but on verb stems it frequently names an action or its result as a feminine noun.

-ce: the agent-or-act suffix

The suffix -ce (masculine animate, declining like the soudce "judge" type) forms a small but important set of agent nouns from verbs, often for administrative or institutional roles.

Instrument nouns: the tool

The third family names the thing that performs the action — the device, machine, or substance. Two suffixes dominate: -č (reused from the agent set, but here for machines) and -dlo.

-č for machines

The same -č that builds řidič ("driver," a person) builds machine names — and here the noun is inanimate. Context and meaning tell you which: a person who drives is a řidič; a machine that vacuums is a vysavač.

-dlo for tools and substances

The suffix -dlo (neuter) builds the names of tools, devices, and especially substances and means used for the action.

Why this matters for English speakers

English collapses a lot of this onto a few overworked suffixes — -er covers both the driver (person) and the cooker (machine), and -ing/-tion cover most actions. Czech keeps the roles more distinct and more predictable, and it loves the zero-suffix noun (vznik, pokles, odjezd) that English can't form at all without changing the word. Recognizing these suffixes lets you decode and even guess vocabulary you've never met: see a verb you know plus -tel and you can bet it's the doer; plus -dlo and it's almost certainly the tool. For the related processes, see verbal prefixation (which feeds many of the result nouns) and deadjectival and abstract nouns.
