I have a question about the possessive "ka." In previous examples regarding her uncle and aunt, it was Julia ki Aunt/Julia kay Uncle. So, ki for female and kay for male, but in this sentence, Julia's husband, it turns into Julia ka Husband. Why?
'Ke' (or 'kay') is the masculine plural possessive ('ki' is feminine singular and plural) and is also used to indicate respect when talking to one's elders, hence its use with Julia's uncle. 'Ka' is the masculine single possessive.
