Znám její sestru.
Znám jejich sestru.
Can you tell the difference 😜?
The key difference lies in the number of people to whom the “sister” belongs: one person in the case of “její sestra” (her sister) and multiple people in the case of “jejich sestra” (their sister).
1. “Znám její sestru” – This sentence means “I know her sister.” The word “její” is a singular possessive pronoun in the third person feminine, referring to one female individual. It indicates that you know the sister of one specific woman or girl.
2. “Znám jejich sestru” – This sentence means “I know their sister.” The word “jejich” is a plural possessive pronoun in the third person, referring to more than one person. This can be a group of people of any gender or a mix of genders. It indicates that you know the sister of several individuals.
The word “jejích” in Czech is a possessive pronoun that means “her” in the 6th plural case.
