"how is work sister?"

Translation: habari za kazi dada?

[Apsa25]

Why not "Habari ya kazi, dada?"

[jeremy131062]

Ya is the singular and za is the plural so I think it is plural because the question is How is work? instead of How was work? Work is an ongoing thing so using "is" refers to all of it versus "was" which refers to just one day.
