Grammar Notes[]

Singular forms of "to be"[]

  • (Já) jsem = I am
  • (Ty) jsi = informal You are
  • (On/Ona/Ono) je = He/She/It is

The subject pronouns Já, Ty and so on may be omitted. If included, it would be interpreted (with some exceptions) as adding emphasis.

Pronoun "to"[]

"To" has several functions:

  • a definite article or demonstrative adjective "that" for singular neuter nouns
    • To zvíře je staré. (The/that animal is old.)
  • As demonstrative attached to singular nouns
    • To je dobré/nové. (It/that is good/new.)
  • As a stand-alone subject of a sentence with a noun in the predicate. The noun can be any gender, not necessarily neuter.
    • To je nový stroj. (It/that is a new machine.)
    • Je to mladá žena. (She is a young woman.)
    • Je to malé dítě. (It is a little child.)
  • As a stand-alone subject of a sentence without a noun in the adjectival predicate. Here the pronoun must agree in number and gender with the adjective:
    • Ta je nová. (That [one] is new.)
    • Ten je nový.
    • To je nové.

Negation[]

  • (Já) nejsem (I am not)
  • (Ty) nejsi (informal You are not)
  • (On/Ona/Ono) není (He/She/It is not)

Czech verbs can usually be negated by adding ne in front but není is one of the rare exceptions.

Yes/no questions[]

Questions inviting a yes/no answer are like statements, with a question mark at the end. In speech, the question is indicated by a rising tone.

Informal vs formal You[]

The ty form is the informal singular. Czech also has a formal you form to be introduced later.
