nie

In a sentence

• Nie idę do sklepu.

  I am not going to the store.

  The word 'nie' is used as a negation of the verb 'idę' (I am going). It indicates that the action of going is not happening.

• To nie jest książka.

  This is not a book.

  Here, 'nie' serves to negate the verb 'jest' (is), suggesting that the subject, 'to' (this), is not what the predicate suggests.

• Nawet jeśli nie pada deszcz, to wezmę parasol.

  Even if it is not raining, I will take an umbrella.

  In this sentence, 'nie' negates the action 'pada' (rains), meaning that the condition of raining is not occurring.
