Жена си or жена му: the reflexive си

In the third person Bulgarian tells his own apart from someone else's.

• си when the owner is the subject of the sentence: Иван обича жена си (Ivan loves his own wife).
• му, ѝ, им when the owner is someone else: Иван познава жена му (Ivan knows his wife, meaning another man's).

The hint names the owner. If it is the same person as the subject, the answer is си; if not, pick му (a man), ѝ (a woman) or им (several people). As with other short possessives, close family in the singular has no article (майка си, брат му), while other nouns keep it (телефона си, колата ѝ). When the owner is I or you, both forms are possible (майка си or майка ми), so every owner in this lesson is he, she or they.
