"If he had not come, she would not have cooked"

Translation: Asingalikuja asingalipika

[snadhelta]

Is there a clear way to tell in Swahili that the subject in the two clauses is different (as English makes clear with the genders)?

[AGreatUserName]

To indicate two different genders, you could say "Mwanaume asingalikuja, mwanamke asingalipika," but I think if you just want to indicate that it's two different people, I think you might use a demonstrative such as huyu for one or the other, but I'm not exactly sure. I think the reasonably interpretation of the Swahili sentence given here is that it's only one person though, so I'm sure the English sentence given is just a bit off and maybe an oversight.
