inspektora

In a sentence

• Widziałem inspektora w biurze.

  I saw the inspector in the office.

  Here the word 'inspektora' is in the accusative case because it is the direct object in the sentence, referring to someone being seen.

• Zadzwoniłem do inspektora w sprawie raportu.

  I called the inspector regarding the report.

  In this sentence, 'inspektora' is in the genitive case, as it follows the preposition 'do' which requires this case.

  The word 'inspektorowi' (declined form of 'inspektor') is in the dative case here, used to indicate the indirect object of the verb.
