Jest and to

Level 2

In Polish, 'to' and 'jest' both translate to 'is', but they serve different functions. 'To' acts like an equals sign for identification (Nominative case), while 'jest' describes states, locations, or professions (Instrumental case for nouns).

How It Works

Understanding the difference between to and jest is essential for building clear Polish sentences.

1. The Definition Pattern: 'Noun + to + Noun'
Use to as a connector when you are defining what something is or equating two things (A = B).

  • Case: Both nouns remain in the Nominative case.
  • Invariable: In this specific pattern, to never changes, even if the nouns are plural (e.g., Psy to zwierzęta). You do not add jest or są here.
  • Alternative: If you use jest instead of to to connect two nouns, the second noun must change to the Instrumental case (e.g., Warszawa jest stolicą).

2. The Description Pattern: 'Subject + jest + Adjective/Location'
Use jest (from the verb być) to describe a subject's properties or where it is.

  • Adjectives: Use jest + Nominative adjective (e.g., Kawa jest gorąca). Warning: You cannot use the to connector to link a specific noun to an adjective (e.g., Kawa to gorąca is incorrect).
  • Location: Always use jest for location (e.g., Kot jest w kuchni).

3. The Demonstrative Pattern: 'To jest...'
When you are pointing at something and saying "This is...", to functions as a demonstrative pronoun.

  • Identification: To jest mój dom (This is my house). In the plural, this becomes To są... (e.g., To są moje klucze).
  • With Adjectives: You can say To jest tanie (This is cheap) when to refers to an unspecified "this thing" or "this situation."

Examples (6)

  1. To jest mój brat.

    This is my brother.

    Word by Word: This is my brother.

    A demonstrative sentence pointing someone out. 'To' acts as 'this' and is followed by 'jest' and the Nominative.

  2. Mój brat jest wysoki.

    My brother is tall.

    Word by Word: My brother is tall.

    When describing a property with an adjective, use 'jest' with the Nominative.

  3. On jest lekarzem.

    He is a doctor.

    Word by Word: He is doctor [Instrumental].

    When using 'jest' to link a person to a noun (like a profession), the noun must be in the Instrumental case.

  4. Warszawa to stolica Polski.

    Warsaw is the capital of Poland.

    Word by Word: Warsaw [is] capital of Poland.

    A definition (A=B). Here 'to' acts as the connector (copula) and both nouns stay in the Nominative.

  5. Psy to zwierzęta.

    Dogs are animals.

    Word by Word: Dogs [are] animals.

    In the 'Noun to Noun' definition pattern, 'to' remains invariable even when the nouns are plural.

  6. To jest gorące.

    This is hot.

    Word by Word: This is hot.

    Here 'to' is a demonstrative pronoun ('this'). You can use it with an adjective, but only when it means 'this thing'.

Common Mistakes

  • Using 'to' with a lone adjective.

    Ten samochód to szybki.
    Ten samochód jest szybki.

    You cannot use 'to' to link a noun to an adjective. You must use 'jest'.

  • Using the Nominative case after 'jest' for a profession.

    On jest nauczyciel.
    On jest nauczycielem.

    When using the verb 'jest' to describe a role or profession, the noun must be in the Instrumental case.

  • Using 'te' where plain identification needs 'to'.

    Different MeaningTe są moje psy.
    To są moje psy.

    Te są moje psy is correct when you point out or contrast ('these are my dogs, those are yours'). For plain identification ('These are my dogs'), Polish normally uses the invariable to: To są moje psy.
