How does it change in a sentence?
The form of the word changes based on its grammatical role in a sentence. Use the nominative singular quis when "who" is the subject of the sentence. If "who" is the direct object of a verb, use the accusative singular quem (whom). Use the genitive singular cuius to say "whose". Finally, use the dative singular cui when "who" is the indirect object, such as in the phrase "to whom".
